Product Summary

The MAX807NCWE is a Full-Featured uP Supervisory Circuit. It reduces the complexity and number of components needed to monitor power-supply and battery-control functions in µP systems. A 70μA supply current makes the MAX807NCWE ideal for use in portable equipment, while a 2ns chip-enable propagation delay and 250mA output current capability (20mA in battery-backup mode) make it suitable for larger, higher-performance equipmen. The applications of the MAX807NCWE are Computers, Controllers, Intelligent Instruments, Critical μP Power Monitoring, Portable/Battery-Powered Equipment.
