Description and Introduction

Power-Supply Monitor with Reset The MAX709SESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (e.g., 4.63V, 4.38V, 3.08V, etc.)  
- **Reset Timeout Period:** Typically 200ms (adjustable in some variants)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX709SESA monitors system voltage and provides a reset signal to the microprocessor if the supply voltage drops below a preset threshold.  
- It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  
- Available in fixed or adjustable threshold versions for flexibility in different applications.  

### **Features:**  
- **Low Power Consumption:** Typically 35μA supply current.  
- **Manual Reset Input:** Allows for external reset control.  
- **Power-On Reset (POR):** Ensures a valid reset signal upon power-up.  
- **Watchdog Timer (in some variants):** Monitors software execution (not present in all models).  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Space-Saving Package:** 8-pin SOIC for compact designs.  

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

Alternative Part Number

  • ADM809SARTZ --: Pin-compatible microprocessor supervisor with active-low reset and similar threshold, widely available and functionally equivalent.
  • TPS3808G30 --: Low-power voltage supervisor with adjustable delay and active-low reset, suitable replacement for supply monitoring applications.
  • MCP131T-300E --: 3.0V reset supervisor in SOT-23 with active-low output, offering comparable reset threshold and low current consumption.
  • ADM809SARTZ-REEL --: Supervisor IC with similar reset threshold and active-low push-pull reset output; widely available and pin-compatible in function.
  • TL7705ACD --: Classic 5V supply voltage supervisor with adjustable reset delay, suitable replacement for power-on reset monitoring.
  • MC33064D-5G --: 5V undervoltage sensing circuit with open-collector reset output, low cost and commonly stocked alternative.
