Description and Introduction

Switching Regulator Controller **Manufacturer:** FUJ (Fujitsu)  

**Part Number:** MB3776APNF  

### **Specifications:**  
- **Type:** Voltage Detector IC  
- **Operating Voltage Range:** 1.5V to 5.5V  
- **Detection Voltage Accuracy:** ±2%  
- **Detection Voltage Options:** Available in multiple fixed levels (specific values depend on variant)  
- **Quiescent Current:** 1.5μA (typical)  
- **Output Configuration:** Open-drain or CMOS output (depends on variant)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-8 (Small Outline Package)  

### **Descriptions:**  
- The MB3776APNF is a low-power voltage detector IC designed for monitoring power supply voltages in electronic systems.  
- It provides a reset signal when the supply voltage drops below a predefined threshold, ensuring system stability.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **High Accuracy:** Tight detection voltage tolerance (±2%).  
- **Wide Operating Voltage Range:** Supports applications from 1.5V to 5.5V.  
- **Compact Package:** SOP-8 for space-constrained designs.  
- **Reliable Reset Operation:** Ensures proper system initialization.  

This information is based on the manufacturer's datasheet for the MB3776APNF. For detailed specifications, refer to the official documentation.

Application Scenarios & Design Considerations

Switching Regulator Controller

Alternative Part Number

  • M51953BFP --: Renesas voltage detector/reset IC with similar reset threshold and open-drain output, commonly used as a direct substitute for Fujitsu MB3776 series supervisors.
  • S-80845CNUA --: ABLIC (Seiko) CMOS voltage detector offering comparable reset threshold accuracy and low current consumption, suitable for replacing MB3776APNF in reset circuits.
  • TC54VC4202ECB --: Microchip voltage supervisor with similar reset function and small package, providing a functional alternative when the original Fujitsu part is unavailable.
  • MC33064P-5 --: Voltage supervisor/reset IC with similar 5V monitoring function and open-collector reset output, widely available and pin-compatible in most applications.
  • TL7705ACP --: Classic 5V supply voltage supervisor with programmable reset delay, functionally equivalent to the MB3776A reset IC family.
  • MAX705CPA --: Microprocessor supervisory circuit providing reset and watchdog functions, suitable replacement when additional monitoring features are acceptable.
