Description and Introduction

5.0 A H-Bridge with Load Current Feedback The MC33887PNBR2 is a monolithic H-Bridge Power IC manufactured by Freescale Semiconductor (now part of NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Freescale (now NXP Semiconductors)  
- **Part Number:** MC33887PNBR2  
- **Type:** H-Bridge Motor Driver  
- **Operating Voltage Range:** 5V to 28V  
- **Continuous Output Current:** 5A (per channel)  
- **Peak Output Current:** 10A (per channel)  
- **On-Resistance (RDS(on)):** 120mΩ (typical, per H-Bridge)  
- **Logic Input Voltage:** 3.3V/5V compatible  
- **PWM Capability:** Up to 10kHz  
- **Protection Features:**  
  - Undervoltage Lockout (UVLO)  
  - Overcurrent Protection (OCP)  
  - Overtemperature Shutdown (TSD)  
- **Package:** 32-Pin QFN (5mm x 5mm)  

### **Descriptions:**  
The MC33887PNBR2 is a high-performance H-Bridge motor driver designed for automotive and industrial applications. It integrates two half-bridges capable of driving DC motors, solenoids, and other inductive loads. The device includes built-in protection features to ensure safe operation under fault conditions.  

### **Features:**  
- **Dual H-Bridge Configuration:** Supports bidirectional motor control.  
- **Low Power Consumption:** Sleep mode for reduced standby current.  
- **Diagnostic Feedback:** Fault status reporting via dedicated pins.  
- **Integrated Charge Pump:** Ensures proper high-side gate drive.  
- **Wide Operating Temperature Range:** -40°C to +125°C (suitable for automotive applications).  

For detailed electrical characteristics and application notes, refer to the official datasheet from NXP (formerly Freescale).

Application Scenarios & Design Considerations

5.0 A H-Bridge with Load Current Feedback

Alternative Part Number

  • L298N --: Dual H-bridge motor driver in a similar power class, widely available and commonly used as a functional substitute for the MC33887 in brushed DC motor drive applications.
  • DRV8871 --: Single H-bridge motor driver with integrated current sensing and comparable voltage/current ratings, suitable as a modern replacement with simpler external circuitry.
  • L6205 --: DMOS dual full-bridge driver with similar drive capability and logic-level control, offering a comparable alternative for bidirectional motor control designs.
  • L293D --: Classic quad half-H driver providing dual H-bridge outputs, easy drop-in for low-to-medium current motor driving where pin compatibility is not critical.
