Abstract
A reset circuit that incorporates a battery monitor and watchdog timer in an integrated circuit is disclosed. A battery monitor having an output indicative of a charge state of a battery and a watchdog timer having an output indicative of an operational state of software being executed by the integrated circuit are connected to reset logic having a reset signal output, wherein the reset logic generates a reset signal on the reset signal output if either the battery monitor output or the watchdog timer output is active.
