Description and Introduction

MICROPOWER UNDERVOLTAGE SENSING CIRCUITS The MC33164P-3 is a voltage monitor IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** Undervoltage Monitor  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Threshold Voltage:** 3.08V (typical)  
- **Hysteresis:** 100mV (typical)  
- **Output Type:** Open Collector  
- **Quiescent Current:** 8μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-92-3  

### **Descriptions and Features:**  
- Designed for monitoring power supply voltages in battery-powered and low-voltage systems.  
- Provides an active-low reset signal when the supply voltage drops below the threshold.  
- Low power consumption makes it suitable for portable applications.  
- Built-in hysteresis prevents output oscillation near the threshold voltage.  
- Open-collector output allows flexibility in interfacing with different logic levels.  

This device is commonly used in power management, microcontroller reset circuits, and battery monitoring applications.

Application Scenarios & Design Considerations

MICROPOWER UNDERVOLTAGE SENSING CIRCUITS

Alternative Part Number

  • TL7705ACP --: Supply voltage supervisor with similar reset threshold and open-drain output, widely available and pin-compatible in many designs.
  • MAX809T --: Low-cost 3-pin voltage supervisor with 3.08V threshold, suitable replacement for 3V monitoring applications.
  • MCP130T-300 --: 3.0V voltage supervisor with active-low reset output, good alternative when exact threshold tolerance is not critical.
  • DS1233-3 --: 3V voltage supervisor/monitor in TO-92 style package, functionally similar reset supervisor with comparable threshold.
  • TL7757 --: 3V supply voltage supervisor with reset output, similar function and package options to the MC33164 series.
  • MCP130-300 --: 3.0V voltage supervisor with active-low reset output, suitable replacement for supply monitoring applications.
