### **Descriptions:**
The MAX791ESE is a comprehensive μP supervisory circuit designed to monitor power supply voltages, manage system resets, and provide backup battery switching. It ensures reliable system operation by generating a reset signal during power-up, power-down, or brownout conditions. It also includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.
### **Features:**
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.
- **Reset Output:** Active-low reset signal with adjustable timeout.
- **Watchdog Timer:** Prevents system lockups with a 1.6s timeout.
- **Backup Battery Switching:** Automatic switchover to backup power.
- **Manual Reset Input:** Allows external reset triggering.
- **Low Quiescent Current:** Minimizes power consumption in battery-backed applications.
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.
