Product Information

Back to top
The TS3004 is a single-supply, second-generation oscillator/timer fully specified to operate at a supply voltage range of 1.55V to 5.25V while consuming less than 2.4μA(max) 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 and TS3006 in the CMOS timer family of the “NanoWatt Analog™” series of high-performance analog integrated circuits.

The TS3004 requires only an RSET = 4.32MΩ resistor to set the FOUT/PWMOUT output period range to between 40μs and 1.398 minutes. To change the output period, an FDIV2:0 combination can be selected. With an on-board 100pF CPWM capacitor, the duty cycle of PWMOUT is set at approximately 75%. Further reduction of the duty cycle is available with an on-board 1MΩ potentiometer. The complete circuit is designed at a supply voltage of 5V. 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.
