Description and Introduction

SUPPLY VOLTAGE MONITOR The ZM33064 is a voltage monitor IC manufactured by ZMDI (Zentrum Mikroelektronik Dresden AG). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Threshold Voltage Options:** Factory-set (e.g., 2.93V, 3.08V, 4.38V, etc.)  
- **Accuracy:** ±2% (typical)  
- **Quiescent Current:** 1.5µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** Open-drain or push-pull (depending on variant)  
- **Package Options:** SOT23-3, SC70-3  

### **Descriptions:**  
- The ZM33064 is a low-power voltage detector designed for monitoring power supply voltages in battery-powered and portable devices.  
- It provides a reset signal when the supply voltage drops below a predefined threshold, ensuring proper system operation.  
- Available in multiple fixed threshold voltages to suit different applications.  

### **Features:**  
- **Ultra-Low Power Consumption:** Ideal for battery-operated devices.  
- **Precision Monitoring:** Ensures reliable system reset.  
- **Small Footprint:** Available in compact SOT23 and SC70 packages.  
- **Wide Operating Voltage Range:** Supports applications from 1.2V to 5.5V.  
- **Hysteresis Included:** Prevents output oscillation near the threshold.  

For exact threshold options and detailed electrical characteristics, refer to the manufacturer's datasheet.

Application Scenarios & Design Considerations

SUPPLY VOLTAGE MONITOR

Alternative Part Number

  • MC33064D-5 --: Same function as the ZM33064 5V supply voltage supervisor with open-collector reset output, widely available and pin-compatible in SOIC-8.
  • MAX809T --: 3-pin microprocessor reset supervisor with active-low reset, a common drop-in style replacement for 5V supervisor applications.
  • TL7705A --: 5V supply voltage supervisor with programmable reset delay, suitable functional substitute when layout flexibility is available.
  • MC33064D-5G --: Same function (5V undervoltage sensing circuit) in SOIC-8, widely available and pin-compatible in most designs.
  • MCP131-315E/TO --: Voltage supervisor with comparable 5V threshold and reset output, suitable drop-in for supply monitoring applications.
  • TL7757CLP --: 5V supply voltage supervisor with open-collector reset output, functionally similar and easy to source.
  • MC34064D-5 --: Equivalent 5V undervoltage sensing IC from the same MC34xxx family, commonly used as a direct substitute.
  • TL7705ACP --: Voltage supervisor with similar 5V monitoring function; different series and package, suitable when layout allows a substitute supervisor IC.
