Description and Introduction

5.0 A H-Bridge with Load Current Feedback The MC33887DWBR2 is a motor driver IC manufactured by Freescale Semiconductor (now part of NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Freescale Semiconductor (NXP)  
- **Part Number:** MC33887DWBR2  
- **Package:** SOIC-20 (DW)  
- **Operating Voltage:** 5V to 28V  
- **Output Current:** Up to 5A continuous (with proper heat sinking)  
- **Peak Output Current:** 10A (transient)  
- **Number of Outputs:** 1 H-Bridge  
- **Control Interface:** Parallel (IN1, IN2, D1, D2)  
- **Protection Features:**  
  - Overcurrent protection  
  - Overtemperature shutdown  
  - Undervoltage lockout  
  - Fault reporting  

### **Descriptions:**
- The MC33887DWBR2 is a monolithic H-Bridge power IC designed for DC motor control applications.  
- It integrates a high-current H-Bridge driver with protection features, making it suitable for automotive and industrial applications.  
- The device can drive motors bidirectionally and supports PWM control for speed regulation.  

### **Features:**
- **Integrated H-Bridge:** Capable of driving DC motors in forward/reverse directions.  
- **Low RDS(on) MOSFETs:** Reduces power dissipation.  
- **Fault Reporting:** Provides diagnostic feedback via the **FS** (Fault Status) pin.  
- **PWM Capable:** Supports pulse-width modulation for speed control.  
- **Wide Operating Voltage Range:** 5V to 28V, suitable for 12V/24V systems.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Undervoltage Lockout (UVLO):** Prevents operation at insufficient supply voltage.  

This IC is commonly used in automotive systems, robotics, and industrial motor control applications.
