Summary of TYPICAL APPLICATION CIRCUIT
The TS3004 is a compact, low-power CMOS timer IC designed for battery-powered applications. It operates on 1.55V to 5.25V with ultra-low current consumption of 1.9μA. The device requires only a single external resistor to set frequencies up to 300kHz and offers significant PCB area and power savings compared to traditional 555 timers.
Parts used in the TS3004 Timer Project:
- TS3004 Single-Supply Timer IC
- External Resistor
- Battery Power Source (1.55V to 5.25V)
The TS3004 is a single-supply, timer IC fully specified to operate over a supply voltage range 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 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, TS3002, TS3003, TS3005, and TS3006 in Touchstone’s CMOS timer family.The TS3004 output period can be user-adjusted from 0.005Hz-300kHz 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 3x3mm TDFN package with an exposed back-side paddle.
