### **Descriptions:**
The MAX736CWE is a comprehensive power-supply monitor and watchdog timer designed to ensure proper system operation in microprocessor-based applications. It monitors the power supply voltage and provides a reset signal to the μP if the voltage falls below a preset threshold. It also includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.
### **Features:**
1. **Power-Supply Monitoring:** Ensures reliable μP operation by generating a reset signal when VCC drops below the threshold.
2. **Programmable Watchdog Timer:** Detects software failures by requiring periodic toggling; triggers reset if not serviced.
3. **Manual Reset Input:** Allows an external push-button to force a system reset.
4. **Battery Backup Support:** Provides a switchover to backup battery for CMOS RAM during power loss.
5. **Power-Fail Comparator:** Early warning of impending power failure.
6. **Adjustable Reset Timeout:** Configurable delay before releasing reset.
7. **Wide Operating Voltage:** Supports standard 5V systems.
8. **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).
