Touchstone Semicondu TS3004DB

TS3004 1.55V to 5.25V, 1.9μA, 3.3μs to 233s Silicon Timer Demo BoardThe demo board is for the evaluation of the TS3004. The TS3004 is an oscillator/timer, fully specified to operate at a supply voltage range of 1.55V to 5.25V while consuming less than 2.4μA 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 is part of the Touchstone’s high-performance “NanoWatt Analog™” series. 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 potentio
