Description and Introduction

Preset -12V output or adjuistable output with 2 resistors, CMOS switching regulator. Output accuracy 5%. The MAX636AESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX636AESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 4.65V, 4.40V, 3.08V, etc., depending on suffix)  
- **Reset Timeout Period:** Adjustable via external capacitor (default: 200ms)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Typically 5μA  

### **Descriptions:**  
The MAX636AESA is a low-power μP voltage monitor designed to ensure proper system operation during power-up, power-down, and brownout conditions. It asserts a reset signal when the supply voltage drops below a preset threshold, keeping the microprocessor in a known state until the voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Monitors VCC and asserts reset when voltage falls below threshold.  
- **Low Power Consumption:** Minimal current draw for battery-powered applications.  
- **Adjustable Reset Timeout:** External capacitor allows customization of reset pulse width.  
- **Manual Reset Input:** Supports external pushbutton reset control.  
- **Guaranteed Reset Output Valid to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.  

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

Description and Introduction

Preset -12V output or adjuistable output with 2 resistors, CMOS switching regulator. Output accuracy 5%. The MAX636AESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-SOIC (150mil)  
- **Type:** Supervisory Circuit  
- **Voltage - Threshold:** 4.65V  
- **Number of Voltages Monitored:** 1  
- **Output Type:** Active Low, Push-Pull  
- **Reset Timeout:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (Max):** 5.5V  
- **Supply Voltage (Min):** 1.2V  

### **Descriptions:**
- The MAX636AESA monitors a microprocessor's power supply voltage and provides a reset signal if the voltage drops below a preset threshold (4.65V).  
- It ensures proper system operation by holding the μP in reset during power-up, power-down, and brownout conditions.  
- The reset signal remains active for at least 200ms after the supply voltage stabilizes above the threshold.  

### **Features:**
- Precision voltage monitoring with a fixed threshold of 4.65V.  
- Push-pull active-low reset output.  
- No external components required for basic operation.  
- Low supply current (typically 15μA).  
- Guaranteed reset valid down to VCC = 1.2V.  
- Immune to short VCC transients.  

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