Overview
The MC13892 is a highly integrated power
management integrated circuit designed
specifically for the i.MX35 and i.MX51
application processor families. It also
supports the i.MX27 and i.MX37 processor
families.
These functions include a battery charging
system for USB and wall charging, a 10 Bit
ADC with a coulomb counter module for
monitoring battery charge, four adjustable
buck regulators for powering the processor
core and memory, 12 adjustable LDOs with
internal/external pass devices and a boost
regulator for RGB LED drivers.
MC13892 also incorporates power control
logic with processor interfacing and event
detection. A real time clock (RTC) function
is provided, including time and day
counters, as well as an alarm function. This
utilizes a 32 kHz clock, either the RC
oscillator or the 32.768 kHz crystal
oscillator as a time base, and is powered
by the coin cell backup supply.
Support is also provided for an external
secure real time clock (SRTC) which may
be integrated on a companion system
processor IC. MC13892 provides all the
circuitry for a resistive touch screen
interface and supports both SPI and I2C
interface. All of these functions have been
incorporated into a highly integrated mixed
signal IC, bidirectional power
management, I/O, and communications
device.
