The MAX791CSE+ by Analog Devices / Maxim Integrated is a microprocessor supervisory circuit designed to simplify power-supply and battery-control monitoring in µP systems. It offers a precision 4.65V voltage monitoring capability, crucial for detecting power-fail warnings and low-battery conditions.
This device provides a 140ms minimum reset timeout and ensures the RESET output is valid down to 1V, even without a battery. Its 50µA supply current makes it suitable for portable equipment, while the 250mA output capability in VCC mode and 25mA in battery-backup mode support various system requirements. The MAX791CSE+ is housed in a 16-SOIC package, suitable for surface mounting.
Key features include an independent watchdog timer, on-board gating of chip-enable signals with a 6ns CE gate propagation delay, and backup-battery switchover functionality. These attributes make it ideal for applications requiring critical µP power monitoring, such as computers and intelligent instruments.
