TS3006: A 1.55V TO 5.25V, 1.9µA, 10kHz TO 300kHz Low Cost Resistor-Tunable Timer IC

The TS3006 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 1.9μA supply current. Requiring only a resistor to set the base output frequency (or output period) at 25kHz (or 40μs) with a 50% duty cycle, the TS3006 timer/oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, low frequency, battery-powered/portable applications, the TS3006 joins the TS3001, TS3002, TS3003, TS3004, and TS3005 in Touchstone’s CMOS timer family in its “NanoWatt Analog™” series of high-performance analog integrated circuits.

Requiring only a resistor to set the output frequency, the TS3006 output frequency can be set from 10kHz to 300kHz without additional components. In addition, the TS3006 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 TS3006 offers up to 84% reduction in pcb area and over three orders of magnitude lower power consumption.

The TS3006 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 8-pin 3x3mm TDFN package with an exposed back-side paddle.
