The MAX793SCSE+ from Analog Devices (Maxim Integrated) is a microprocessor supervisory circuit designed to monitor and control the activities of +3.0V/+3.3V microprocessors. It offers features such as backup-battery switchover, low-line indication, microprocessor reset, write protection for CMOS RAM, and a watchdog timer.
Key electrical specifications include a supply voltage of 2.925V, active high/active low reset functionality, and a reset timeout of 140ms minimum. The device monitors a single voltage and provides open drain, push-pull output.
This supervisory circuit is suitable for applications requiring critical µP power monitoring, such as battery-powered computers and controllers, embedded controllers, and portable equipment. The MAX793SCSE+ is available in a 16-SOIC package and is designed for surface mount applications.
Features like backup-battery power switching, where the battery voltage can exceed VCC, and an independent watchdog timer with a 1.6s timeout enhance system reliability. The chip-enable gating offers a maximum propagation delay of 7ns.
