Low Power Timers
Silicon Labs low power timer family includes the industry’s first and only single-supply CMOS oscillator fully specified to operate at 1 V while consuming a 1μA supply current at an output frequency of 25 kHz (TS3001, TS3002). These oscillators are compact, easy-to-use and versatile. Optimized for ultra-long life, battery-powered applications, these low power timers can operate from single-supply voltages from 0.9 V to 1.8 V. The family also includes parts that operate from 1.55V to 5.5V supplies and consume less than 2μA.
Requiring only a resistor and a capacitor to set the output frequency, the TS3002 represents a 66% reduction in pcb area and a factor-of-10 reduction in power consumption over other CMOS-based integrated circuit oscillators. When compared against industry-standard 555-timer-based products, the TS3002 offers up to 93% reduction in pcb area and four orders of magnitude lower power consumption.The TS3002 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 8-pin 2 x 2 mm TDFN package with an exposed back-side paddle.
