Description and Introduction

CMOS fixed +5V output voltage,adjustable output with 2 resistors step-up switching regulator. 5% output accuracy. The MAX631ACPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Part Number:** MAX631ACPA  
- **Type:** μP (Microprocessor) Supervisory Circuit  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (specific voltage thresholds available in the MAX631x series)  
- **Reset Timeout Period:** Adjustable or fixed (depends on variant)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)  
- **Quiescent Current:** Low (typically a few μA)  

### **Descriptions:**  
- Monitors system power supply voltage and provides a reset signal to the microprocessor when the voltage falls below a preset threshold.  
- Ensures proper system operation by holding the microprocessor in reset during power-up, power-down, or brownout conditions.  
- Features manual reset input for external system control.  

### **Features:**  
- **Power-On Reset (POR) Generator:** Ensures proper initialization of the μP.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Low Quiescent Current:** Suitable for battery-powered applications.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **No External Components Required:** Simplifies circuit design.  

For exact reset threshold voltages and additional details, refer to the official datasheet from Maxim Integrated/Analog Devices.
