The MCP1320T-29LE/OT is a Voltage Supervisor designed to keep a microcontroller in Reset until the system voltage has reached and stabilized at the proper level for reliable system operation. These devices also operate as protection from brown-out conditions when the system supply voltage drops below a safe operating level. Some MCP131X/2X family members include a Watchdog Timer feature that after being enabled (by a falling edge on the WDI pin), monitors the WDI pin for falling or rising edges. If an edge transition is not detected within the expected time frame, the MCP131X/2X devices will force the reset pin active. This is useful to ensure that the embedded system's host controller program is operating as expected.
