Description and Introduction

MicroPower UnderVoltage Sensing Circuit The MC33164P-5RP is a voltage monitor IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** Undervoltage Monitor  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Threshold Voltage (Vth):** 4.55V (fixed)  
- **Hysteresis:** 150mV (typical)  
- **Output Type:** Open Drain  
- **Quiescent Current:** 8µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-92-3 (Pinning: 1-GND, 2-OUT, 3-VCC)  

### **Descriptions and Features:**  
- Monitors power supply voltages for undervoltage conditions.  
- Provides a reset signal when VCC falls below the threshold.  
- Open-drain output requires an external pull-up resistor.  
- Low power consumption for battery-operated applications.  
- Fixed threshold with built-in hysteresis for noise immunity.  
- Suitable for automotive, industrial, and consumer electronics.  

This IC is commonly used in power management circuits to ensure proper system operation.

Alternative Part Number

  • MCP130-475DI/TO --: Voltage supervisor with 4.75V trip point in TO-92 package, functionally similar to the MC33164-5 reset supervisor.
  • DS1233Z-5+ --: 5V EconoReset supervisor providing reset output, a common cross for MC33164-5 type supervisors.
  • TC54VC5002EZB --: 5.0V voltage detector in TO-92, comparable threshold and output behavior for reset/supervisory use.
  • TL7705ACP --: Supply voltage supervisor with 5V threshold and reset output, functionally similar to the MC33164 series; widely available and well documented.
  • MAX809SEUR+T --: 3-pin microprocessor reset supervisor with active-low reset, comparable 5V monitoring function in a compact SOT-23 package.
  • MCP130-450HI/TO --: Voltage supervisor with 4.5V trip point and active-low reset, suitable replacement for 5V system reset monitoring.
