Description and Introduction

MICROPOWER UNDERVOLTAGE SENSING CIRCUITS The MC34164P-3 is a voltage monitor IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** Undervoltage Monitor  
- **Package:** PDIP-3  
- **Operating Voltage Range:** 1.0V to 24V  
- **Threshold Voltage (Vth):** 3.0V (fixed)  
- **Hysteresis:** Typically 50mV  
- **Output Type:** Open Collector  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MC34164P-3 is designed to monitor power supply voltages and provide a reset signal when the voltage drops below the preset threshold (3.0V). It is commonly used in microprocessor and microcontroller-based systems to ensure proper power-up and power-down sequences.  

### **Features:**  
- **Fixed Threshold Voltage (3.0V)**  
- **Low Power Consumption**  
- **Open-Collector Output (Requires Pull-Up Resistor)**  
- **Wide Operating Voltage Range (1.0V to 24V)**  
- **Built-in Hysteresis for Noise Immunity**  
- **Industrial Temperature Range (-40°C to +85°C)**  
- **3-Pin Package for Simple Integration**  

This IC is suitable for battery-powered applications, power supply monitoring, and system reset functions.

Alternative Part Number

  • MCP131T-300E/TO --: 3.0V voltage supervisor with open-drain reset output in TO-92, functionally equivalent to the MC34164P-3.
  • MAX809REUR+T --: 3.0V microprocessor reset supervisor with active-low reset, similar function and threshold in a small package.
  • TL7705ACP --: Widely available supply voltage supervisor with adjustable threshold, suitable replacement for 3V reset monitoring applications.
  • MAX809REUS+T --: 3.0V-class reset supervisor in SOT-23, widely used alternative with compatible reset threshold and active-low output, though package differs from TO-92.
