The Microchip Technology TC1232COE is a fully-integrated processor supervisor IC. It provides essential functions for safeguarding processor operation, including precision power on/off Reset control and an adjustable watchdog timer. The device ensures stable system start-up by holding the processor in a Reset state for a minimum of 250 ms after VCC is within tolerance.
Microprocessor sanity is monitored by the on-board watchdog circuit, which requires a periodic low-going signal on the ST input. Failure to provide this signal within the selected time-out period (150 ms, 600 ms, or 1200 ms) triggers a processor Reset. The TC1232COE also features a debounced manual reset input for external override.
This supervisor operates within a voltage range of 4.0V to 5.5V. It is packaged in a space-saving 16-SOIC (0.295", 7.50mm Width) package and requires no external components. The device supports active high/active low reset signals and has voltage thresholds at 4.37V and 4.62V.
Key electrical characteristics include a maximum supply voltage of 5.5V and a minimum supply voltage of 4V. The operating supply current is typically 200 µA, with a quiescent current of 50 µA. The reset timeout is a minimum of 250 ms, and the watchdog timer offers selectable timeouts of 150 ms, 600 ms, or 1.2s.
