The MAX793RCSE by Analog Devices is a microprocessor supervisory circuit designed to monitor and control the activities of +3.0V/+3.3V microprocessors. It provides essential features such as backup-battery switchover, low-line indication, microprocessor reset, and a watchdog timer.
Key electrical specifications include a precision supply-voltage monitor with a reset assertion guaranteed down to VCC = 1V. The device supports backup-battery power switching, allowing battery voltage to exceed VCC, and features on-board gating of chip-enable signals with a maximum propagation delay of 7ns. It also includes an independent watchdog timer with a typical 1.6s timeout and a manual reset input.
This supervisory circuit is suitable for applications requiring critical µP power monitoring, such as battery-powered computers and controllers, embedded controllers, intelligent controllers, and portable equipment. The MAX793RCSE is available in a 16-pin SOIC package, designed for surface mounting.
The MAX793/MAX794/MAX795 family offers fixed or adjustable reset trip voltages. The MAX793/MAX795 provide fixed thresholds, while the MAX794's threshold is externally adjustable. The MAX793/MAX794 are available in 16-pin DIP and narrow SO packages, and the MAX795 comes in 8-pin DIP and SO packages.

The MAX793RCSE supports 3.0V/3.3V systems with a nominal supply voltage of 3.3V.
The reset threshold voltage is nominally 3.0V, but the part number suffix 'R' indicates a range of 2.55V to 2.70V per the datasheet.
The watchdog timer timeout is typically 1.6 seconds.
The reset timeout is a minimum of 140ms.
It is available in a 16-SOIC surface-mount package (0.154", 3.90mm width).
The operating temperature range is 0°C to 70°C.
The reset output is available in active-high and active-low configurations, with open-drain and push-pull options.
