MIC1832MY Power Management ICs - PMIC by Microchip Technology
Microprocessor Supervisor with Manual Reset, Watchdog Timer, and Dual Reset Output
| Status: | Active |
|---|---|
| Series: | MIC1832 |
| RoHS: | Compliant |
The MIC1832 is a multifunction circuit which monitors microprocessor activity, external reset and power supplies in microprocessor based systems. The circuit functions include a watchdog time, power supply monitor, microprocessor reset, and manual pushbutton reset input.
The power supply line is monitored with a comparator and an internal voltage reference. /RST is forced low when an out-of-tolerance condition exists and remains asserted for at least 250ms after VCC rises above the threshold voltage (2.55V or 2.88V). The /RST pin will remain logic low with VCC as low as 1.4V.
The Watchdog input (/ST) monitors µP activity and will assert /RST if no µP activity has occurred with in the watchdog timeout period. The watchdog timeout period is selectable with nominal period of 150, 600, 1200 milliseconds.
