TS3004 Oscillator/Timer


Touchstone Semiconductor's TS3004 is a 1.5 V to 5 V, 6 µW pin-programmable FOUT silicon oscillator/timer


Touchstone Semiconductor's TS3004 Oscillator/TimerThe TS3004 is a single-supply, second-generation oscillator/timer from Touchstone Semiconductor. The device is fully specified to operate at a supply voltage of 3 V while consuming 2 µA supply current. Requiring only a resistor to set the base output frequency (or output period) at 25 kHz (or 40 µs) with a 50% duty cycle, the TS3004 timer/oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, low frequency, battery-powered/portable applications, the TS3004 joins the TS3001 and the TS3002 in Touchstone’s CMOS timer family in its "NanoWatt Analog™" series of high-performance analog integrated circuits. The TS3004 operates on single-supply voltages from 1.5 V to 5.25 V.

Including an internal 3-bit counter, the TS3004 output period can be user-adjusted from 10 µs to 210 s without additional components. In addition, the TS3004 represents a 25% reduction in PCB area and a factor-of-10 lower power consumption over other CMOS-based integrated circuit oscillators/timers. When compared against industry-standard 555-timer-based products, the TS3004 offers up to 84% reduction in PCB area and over three orders of magnitude lower power consumption.

The TS3004 is fully specified over the -40°C to +85°C temperature range, and is available in a low profile, 10-pin, 3 mm x 3 mm TDFN package with an exposed back side paddle.
