DESCRIPTION

The TS3001 is a single-supply CMOS oscillator/timer fully specified to operate at 1V while consuming a 1µA supply current at an output frequency of 25kHz. This oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, battery-powered applications, the TS3001 is the newest Touchstone’s oscillator/timer in the “NanoWatt Analog™” high-performance analog integrated circuits portfolio. The TS3001 can operate from single-supply voltages from 0.9V to 1.8V.

Requiring only a resistor to set the output frequency, the TS3001 represents a 66% reduction in pcb area and a factor-of-10 reduction is power consumption over other CMOS-based integrated circuit oscillators. When compared against industry-standard 555-timer-based products, the TS3001 offer up to 93% reduction in pcb area and four orders of magnitude lower power consumption.

The TS3001 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 8-pin 2x2mm TDFN package with an exposed back-side paddle.
