Product Details
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

250mA Output in VCC Mode
25mA Output in Battery-Backup Mode
♦ On-Board Gating of Chip-Enable Signals
Memory Write-Cycle Completion
6ns CE Gate Propagation Delay
♦ MaxCap‰ or SuperCap‰ Compatible
♦ Voltage Monitor for Power-Fail or Low-Battery Warning
♦ Backup-Battery Monitor
♦ Guaranteed –R—E—S—E—T– Valid to VCC = 1V
