Micropower Supply Voltage Supervisor, TLC7705IP, Texas Instruments

The TLC7705IP is a micropower supply-voltage supervisor that provides reset control for microcomputer and microprocessor systems. During power-up, the RESET output is asserted when VDD reaches 1 V. Once VDD rises above the minimum operating voltage (≥2 V), the device monitors the SENSE input voltage (VI(SENSE)) and keeps RESET active as long as VI(SENSE) remains below the threshold. An internal timer delays de-assertion of RESET to ensure a proper system reset.
