Additional Details

The specific voltage detection threshold, reset timeout duration, and operating temperature range would be specified in the M65135FP datasheet. The datasheet also details the required external components, such as pull-up resistors for the open-drain output. Proper decoupling capacitors should be used close to the power supply pins to ensure stable operation.
