Description and Introduction

Preset -12V output or adjuistable output with 2 resistors, CMOS switching regulator. Output accuracy 5%. The MAX636ACSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **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:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 10μA (typical)  

### **Descriptions:**  
- Monitors μP power supply and generates a reset signal if voltage drops below a preset threshold.  
- Ensures proper system initialization by holding the μP in reset during power-up, power-down, or brownout conditions.  
- Features a manual reset input for external system control.  

### **Features:**  
- Precision voltage monitoring for reliable μP supervision.  
- Low power consumption.  
- No external components required (except for manual reset, if used).  
- Guaranteed reset output valid down to VCC = 1V.  
- Push-pull reset output (active-low).  

For exact reset threshold voltage options, refer to the manufacturer's datasheet for the specific suffix (e.g., MAX636ACSA+T).

Description and Introduction

Preset -12V output or adjuistable output with 2 resistors, CMOS switching regulator. Output accuracy 5%. The MAX636ACSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX636ACSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Factory-set (e.g., 4.63V, 4.38V, 3.08V, 2.93V, etc.)  
- **Reset Timeout Period:** Adjustable (typically 200ms)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Typically 5μA  
- **Output Type:** Active-low reset (open-drain or push-pull, depending on variant)  

### **Descriptions:**  
The MAX636ACSA is a low-power microprocessor supervisory circuit designed to monitor system voltage levels and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It ensures reliable system operation by holding the μP in reset until the supply voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset triggering at specified thresholds.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Adjustable Reset Timeout:** Configurable via an external capacitor.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Wide Supply Range:** Operates from 1.2V to 5.5V.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  

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