Description and Introduction

4-Pin Micropower Voltage Monitors The MAX836EUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual data from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX836EUS-T  
- **Package:** SOT-23-4  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**
- The MAX836EUS-T is a low-power microprocessor reset circuit designed to monitor system voltage and provide a reset signal to the μP if the supply voltage drops below a preset threshold.  
- It ensures proper system operation by holding the μP in reset during power-up, power-down, or brownout conditions.  
- The device is available in a small SOT-23-4 package, making it suitable for space-constrained applications.  

### **Features:**
- **Low Power Consumption:** Only 5μA typical supply current.  
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy ensures reliable reset operation.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Manual Reset Input:** Allows for external reset control.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **No External Components Required:** Simplifies circuit design.  
- **Small Form Factor:** Available in a compact SOT-23-4 package.  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

4-Pin Micropower Voltage Monitors

Alternative Part Number

  • ADM809LARTZ-REEL --: Pin-compatible voltage supervisor in SOT-23 with similar reset threshold and open-drain output, widely available and functionally equivalent.
  • TPS3808G01DBVR --: Adjustable-threshold supervisor in SOT-23-6 with programmable delay, suitable replacement for supply monitoring in the same footprint class.
  • MCP1316T-29FE/OT --: Low-power voltage supervisor with fixed 2.9V threshold in SOT-23-5, offering comparable reset functionality and low quiescent current.
  • MCP131T-300E/TO --: Low-cost 3.0V voltage supervisor with active-low reset in TO-92/SOT-23, offering comparable reset functionality for simple monitoring.
