MAX791EJE规格书详情
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.
Features
♦ Precision 4.65V Voltage Monitoring
♦ 200ms Power-OK/Reset Time Delay
♦ Independent Watchdog Timer—Preset or Adjustable
♦ 1µA Standby Current
