Description and Introduction

5.0 A H-Bridge with Load Current Feedback The MC33887PNB is a monolithic H-Bridge Power IC manufactured by Freescale Semiconductor (now NXP Semiconductors). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Freescale (now part of NXP Semiconductors)  
- **Package:** PNB (PowerPAD SOIC-20)  
- **Operating Voltage:** 5V to 40V  
- **Output Current:** Up to 5A continuous (with proper heat sinking)  
- **Peak Current:** Up to 10A (transient)  
- **On-Resistance (RDS(ON)):** 120mΩ (typical) per H-Bridge  
- **PWM Frequency:** Up to 10kHz  
- **Control Interface:** Parallel CMOS/TTL-compatible inputs  
- **Protection Features:**  
  - Undervoltage shutdown  
  - Overcurrent protection  
  - Thermal shutdown  
  - Fault reporting  

### **Descriptions:**  
The MC33887PNB is a high-current H-Bridge motor driver designed for automotive and industrial applications. It integrates two half-bridge drivers with protection features, making it suitable for driving DC motors, solenoids, and other inductive loads.  

### **Features:**  
- **Integrated H-Bridge:** Drives bidirectional DC motors.  
- **Low Power Consumption:** Sleep mode with minimal current draw.  
- **Diagnostic Output:** Provides fault status (overcurrent, thermal shutdown).  
- **CMOS/TTL Inputs:** Compatible with microcontrollers and logic circuits.  
- **PowerPAD Package:** Enhances thermal performance for high-current applications.  
- **Wide Operating Range:** Supports 5V to 40V supply voltage.  

This information is strictly based on the manufacturer's datasheet.

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 in motor control designs.
  • L6205 --: DMOS dual full-bridge driver with similar H-bridge topology and current capability, offering a comparable alternative for bidirectional motor drive circuits.
  • L293D --: Quad half-H driver capable of driving two DC motors or one stepper, a low-cost drop-in style alternative for lower-current motor drive designs.
