The TS3005 is a single-supply, second-generation Touchstone Semi oscillator/timer fully specified to operate over a supply voltage of 1.55V to 5.25V while consuming 1.35μA supply current. Requiring only a resistor to set the base output frequency (or output period) at 49Hz (or 20.5ms) with a 50% duty cycle, the TS3005 timer/oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, low frequency, battery-powered/portable applications, the TS3005 joins the TS3001, TS3002, TS3003, TS3004, and TS3006 in Touchstone’s CMOS timer family in its “NanoWatt Analog™” series of high-performance analog integrated circuits.
Including an internal 3-bit counter, the TS3005 output period can be user-adjusted from 1.7ms to 30hr without additional components. In addition, the TS3005 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 TS3005 offers up to 84% reduction in pcb area and over three orders of magnitude lower power consumption.
The TS3005 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 10-pin 3x3mm TDFN package with an exposed back-side paddle.
