CAT4104
700 mA Quad Channel
Constant Current LED Driver
Description
The CAT4104 provides four matched low dropout current sinks to
drive highbrightness LED strings up to 175 mA per channel. The
LED channel current is set by an external resistor connected to the
RSET pin. The LED pins are compatible with high voltage up to 25 V
supporting applications with long strings of LEDs.
The EN/PWM logic input supports the device enable and high
frequency external Pulse Width Modulation (PWM) dimming control.
Thermal shutdown protection is incorporated in the device to
disable the LED outputs whenever the die temperature exceeds 150°C.
The device is available in the 8pad TDFN 2 mm x 3 mm package
and the SOIC 8Lead 150 mil wide package.

EN/PWM Operation
The EN/PWM pin has two primary functions. One
function enables and disables the device. The other function
turns the LED channels on and off for PWM dimming
control. The device has a very fast turnon time (from
EN/PWM rising to LED on) and allows “instant on” when
dimming LED using a PWM signal.
Accurate linear dimming is compatible with PWM
frequencies from 100 Hz to 5 kHz for PWM duty cycle
down to 1%. PWM frequencies up to 50 kHz can be
supported for duty cycles greater than 10%.
When performing a combination of low frequencies and
small duty cycles, the device may enter shutdown mode.
This has no effect on the dimming accuracy, because the
turnon time TPS is very short, in the range of 1 ms.
To ensure that PWM pulses are recognized, pulse width
low time TLO should be longer than 1 ms. The CAT4104
enters a “zero current” shutdown mode after a 4 ms delay
(typical) when EN/PWM is held low.

Pin Function
VIN is the supply pin for the device. A small 0.1 mF ceramic
bypass capacitor is optional for noisy environments.
Whenever the input supply falls below the undervoltage
threshold, all LED channels are automatically disabled.
EN/PWM is the enable and one wire dimming input for all
LED channels. Guaranteed levels of logic high and logic low
are set at 1.3 V and 0.4 V respectively. When EN/PWM is
initially taken high, the device becomes enabled and all LED
currents are set at a gain of 100 times the current in RSET.
To place the device into zero current shutdown mode, the
EN/PWM pin must be held low for 4 ms typical.
LED1 to LED4 provide individual regulated currents for
each of the LED cathodes. There pins enter a high
impedance zero current state whenver the device is placed
in shutdown mode.
RSET pin is connected to an external resistor to set the LED
channel current. The ground side of the external resistor
should be star connected to the GND of the PCB. The pin
source current mirrors the current to the LED sinks. The
voltage at this pin is regulated to 1.2 V.
GND is the ground reference for the device. The pin must be
connected to the ground plane on the PCB.
TAB (TDFN 8Lead Only) is the exposed pad underneath
the package. For best thermal performance, the tab should be
soldered to the PCB and connected to the ground plane.

Basic Operation
The CAT4104 has four tightly matched current sinks to
regulate LED current in each channel. The LED current in
the four channels is mirrored from the current flowing
through the RSET pin according to the following formula:
ILED ^100 1.2 V
RSET
Table 6 shows standard resistor values for RSET and the
corresponding LED current.

60 2.10
100 1.27
175 0.768
Tight current regulation for all channels is possible over
a wide range of input voltages and LED voltages due to
independent current sensing circuitry on each channel.
Each LED channel needs a minimum of 400 mV
headroom to sink constant regulated current up to 175 mA.
If the input supply falls below 2 V, the undervoltage
lockout circuit disables all LED channels. Any unused LED
channels should be left open.
For applications requiring more than 175 mA current,
LED channels can be tied together to sink up to a total of
700 mA from the one device.
The LED channels can withstand voltages up to 25 V. This
makes the device ideal for driving long strings of high power
LEDs from a high voltage source.

Application Information
Single 12 V Supply
The circuit shown in Figure 20 shows how to power the
LEDs from a single 12 V supply using the CAT4104. Three
external components are needed to create a lower voltage
necessary for the VIN pin (below 5.5 V). The resistor R2 and
zener diode Z provide a regulated voltage while the
quiescent current runs through the NChannel transistor M.
The recommended parts are ON Semiconductor MM3Z6V2
zener diode (in SOD323 package), and 2N7002L
NChannel transistor (in SOT23).

Daylight Detection
The circuit in Figure 21 shows how to use CAT4104 in an
automatic light sensor application. The light sensor allows
the CAT4104 to be enabled during the day and disabled
during the night. Two external components are required to
configure the part for ambient light detection and conserve
power. Resistor R1 sets the bias for the light sensor. The
recommended part is Microsemi LX1972 light sensor. For
best performance, the LED light should not interfere with
the light sensor.

Nightlight Detection
The circuit shown in Figure 22 illustrates how to use the
CAT4104 in an automatic night light application. The light
sensor allows the CAT4104 to be disabled during the day and
enabled during the night. Five external components are
needed to properly configure the part for night detection.
Resistor R3 limits the quiescent current through the
NChannel transistor M. Resistors R1 and R2 act as a
voltage divider to create the required voltage to turn on
transistor M, which disables the CAT4104. The
recommended parts are ON Semiconductor 2N7002L
NChannel transistor (in SOT23) and the Microsemi
LX1972 light sensor. For best performance, the LED light
should not interfere with the light sensor.

LED Current Derating
The circuit shown in Figure 23 provides LED temperature
derating to avoid overdriving the LED under high ambient
temperatures, by reducing the LED current to protect the
LED from overheating. The positive thermo coefficient
(PTC) thermistor RPTC is used for temperature sensing and
should be located near the LED. As the temperature of
RPTC increases, the gate voltage of the MOSFET M1
decreases. This causes the transistor M1 onresistance to
increase which results in a reduction of the LED current. The
circuit is powered from a single VCC voltage of 5 V. The
recommended parts are Vishay 70°C thermistor
PTCSS12T071DTE and ON Semiconductor 2N7002L
NChannel transistor (in SOT23).
The PCB and heatsink for the LED should be designed
such that the LED current is constant within the normal
temperature range. But as soon as the ambient temperature
exceeds a max threshold, the LED current drops to protect
the LEDs from overheating.

Power Dissipation
The power dissipation (PD) of the CAT4104 can be
calculated as follows:
PD+(VIN IIN))S(VLEDN ILEDN)
where VLEDN is the voltage at the LED pin, and ILEDN is the
LED current. Combinations of high VLEDN voltage and high
ambient temperature can cause the CAT4104 to enter
thermal shutdown. In applications where VLEDN is high, a
resistor can be inserted in series with the LED string to lower
the power dissipation PD.
Thermal dissipation of the junction heat consists
primarily of two paths in series. The first path is the junction
to the case (qJC) thermal resistance which is defined by the
package style, and the second path is the case to ambient
(qCA) thermal resistance, which is dependent on board
layout. The overall junction to ambient (qJA) thermal
resistance is equal to:
qJA +qJC )qCA
For a given package style and board layout, the operating
junction temperature TJ is a function of the power
dissipation PD, and the ambient temperature, resulting in the
following equation:
TJ+TAMB )PD(qJC )qCA)+TAMB )PDqJA
When mounted on a doublesided printed circuit board
with two square inches of copper allocated for “heat
spreading”, the resulting qJA is about 90°C/W for the
TDFN8 package, and 160°C/W for the SOIC8 package.
For example, at 60°C ambient temperature, the maximum
power dissipation for the TDFN8 is calculated as follow:
PDmax +
TJmax *TAMB
qJA
+150 *60
90 +1W
Recommended Layout
A small ceramic capacitor should be placed as close as
possible to the driver VIN pin. The RSET resistor should
have a Kelvin connection to the GND pin of the CAT4104.
The board layout should provide good thermal dissipation
through the PCB. In the case of the CAT4104VP2 in the
TDFN package, a via can be used to connect the center tab
to a large ground plane underneath as shown on Figure 24.
