Switching power converter controller providing control of plurality of switching power converters which provide power to a host microprocessor. A watchdog timer included in the switching power converter controller is configured to countdown a timer unless it receives a reset signal from the host microprocessor. The switching power converter controller is configured to assert a reset command for the host microprocessor if the watchdog timer expires and to not de-assert the reset command until the plurality of switching power converters are operating as desired.

Switching power converter controller with watchdog timer

A switching power converter controller controls a plurality of switching power converters which provide power to a host microprocessor. A watchdog timer in the switching power converter controller counts down a timer unless it receives reset signals from the host microprocessor and the watchdog timer issues an interrupt to the microprocessor if the watchdog timer expires. The microprocessor in the switching power converter controller provides a reset command to the host microprocessor in response to receipt of the interrupt. If the host microprocessor does not respond to the reset command, the microprocessor causes the switching power supply controller to power down the power converters.
