General Description
The MAX791 microprocessor (μP) supervisory circuit reduces the complexity and number of components needed to monitor power-supply and battery-control functions in μP systems. The 50μA supply current makes the MAX791 ideal for use in portable equipment, while the 6ns chip-enable propagation delay and 250mA output capability (25mA in battery-backup mode) make it suitable for larger, higher-performance equipment.
