Microprocessor Supervisory Circuits The MAX693AEPE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Manufacturer:** Maxim Integrated
- **Part Number:** MAX693AEPE
- **Type:** Microprocessor Supervisory Circuit
- **Package:** 16-Pin PDIP (Plastic Dual In-Line Package)
- **Operating Voltage Range:** 1.2V to 5.5V
- **Reset Threshold Accuracy:** ±1.5% (typical)
- **Reset Timeout Period:** Adjustable or fixed (depends on configuration)
- **Watchdog Timer:** Yes (programmable)

### **Descriptions:**
The MAX693AEPE is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal when the supply voltage falls below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets. The device also provides battery backup support for critical memory or real-time clock (RTC) applications.
### **Features:**
1. **Voltage Monitoring:** Monitors VCC and generates a reset signal if voltage drops below the threshold.
2. **Watchdog Timer:** Detects system lockups and triggers a reset if not cleared within a set time.
3. **Manual Reset Input:** Allows for external reset initiation via a pushbutton.
4. **Battery Backup Support:** Automatic switchover to backup battery for power-fail protection.
5. **Low Power Consumption:** Minimizes power draw in battery-backed applications.
6. **Adjustable Reset Timeout:** Configurable reset pulse width.
7. **Wide Operating Voltage Range:** Supports systems from 1.2V to 5.5V.
8. **Industrial Temperature Range:** Operates reliably in harsh environments (-40°C to +85°C).
