Description and Introduction

Low-Cost, µP Supervisory Circuits The MAX705CUA+ is a microprocessor (μP) supervisory circuit manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** MAXIM (Analog Devices)  
- **Package:** 8-pin μMAX  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 35μA (typ)  

### **Descriptions:**
The MAX705CUA+ monitors power supply voltages for μP and digital systems, ensuring proper operation during power-up, power-down, and brownout conditions. It provides a reset signal to the μP when the supply voltage falls below a preset threshold, preventing erratic behavior.

### **Features:**
- **Manual Reset Input:** Allows external pushbutton reset.  
- **Low Power Consumption:** 35μA typical supply current.  
- **Precision Voltage Monitoring:** Fixed or adjustable threshold options.  
- **Guaranteed Reset Assertion:** Down to VCC = 1V.  
- **Small Form Factor:** 8-pin μMAX package.  
- **Wide Operating Voltage Range:** 1.2V to 5.5V.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable power monitoring is critical.
