Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The MAX708REUA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)
- **Part Number:** MAX708REUA+
- **Package:** 8-pin μMAX
- **Operating Voltage Range:** 1.2V to 5.5V
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 4.38V, 4.63V)
- **Reset Timeout Period:** 200ms (typical)

- **Watchdog Timer:** Yes (1.6s typical timeout)

### **Descriptions:**
The MAX708REUA+ is a precision voltage monitor designed to ensure proper system operation in microprocessor-based applications. It provides reset signals during power-up, power-down, and brownout conditions. The device includes a watchdog timer, manual reset input, and a power-fail comparator for monitoring secondary power supplies.

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset generation.
- **Adjustable or Fixed Reset Thresholds:** Multiple options for different voltage levels.
- **Low Power Consumption:** 35μA typical quiescent current.
- **Manual Reset Input:** Allows external reset triggering.
- **Power-Fail Comparator:** Monitors an auxiliary power supply.
- **Watchdog Timer:** Resets the system if software fails to toggle within a set time.
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.
- **Small Footprint:** 8-pin μMAX package for space-constrained applications.

This information is based solely on the manufacturer's datasheet and specifications.
