Description and Introduction

Power Supply Monitor The MB3771PF is a power supply monitor IC manufactured by Fujitsu. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Fujitsu  

### **Description:**  
The MB3771PF is a power supply monitoring IC designed to monitor system voltages and provide reset signals when voltage levels fall below specified thresholds. It is commonly used in microprocessor-based systems to ensure stable operation.  

### **Features:**  
1. **Voltage Monitoring:** Monitors multiple power supply voltages (e.g., +5V, +3.3V).  
2. **Adjustable Threshold:** Allows setting custom voltage detection levels.  
3. **Reset Output:** Provides a reset signal when voltage drops below the threshold.  
4. **Low Power Consumption:** Operates efficiently with minimal power draw.  
5. **Wide Operating Voltage Range:** Supports monitoring in various voltage conditions.  
6. **Manual Reset Input:** Includes a pin for external reset triggering.  
7. **Compact Package:** Typically available in a DIP or SOP package.  

### **Specifications:**  
- **Supply Voltage Range:** Typically 1.8V to 5.5V (exact range may vary).  
- **Reset Threshold Accuracy:** High precision (e.g., ±2%).  
- **Operating Temperature Range:** Usually -40°C to +85°C.  
- **Output Type:** Open-drain or push-pull reset output (depending on variant).  

For exact electrical characteristics and pin configurations, refer to the official Fujitsu datasheet.
