Description and Introduction

5.0 A H-Bridge with Load Current Feedback The MC33887DWB is a monolithic H-Bridge Power IC manufactured by Freescale Semiconductor (now part of NXP Semiconductors). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Freescale Semiconductor  
- **Package:** SOIC-20 (DWB)  
- **Operating Voltage Range:** 5V to 28V  
- **Continuous Output Current:** 5A  
- **Peak Output Current:** 10A  
- **RDS(on) (Per MOSFET):** 120 mΩ (typical)  
- **PWM Frequency Capability:** Up to 20 kHz  
- **Logic Input Voltage:** 3.3V or 5V compatible  
- **Fault Protection Features:** Overcurrent, Overtemperature, Undervoltage lockout  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**
- The MC33887DWB is a high-current H-Bridge driver designed for DC motor and inductive load control applications.  
- It integrates two N-channel MOSFETs per half-bridge, providing bidirectional drive capability.  
- The device includes protection features to ensure safe operation under fault conditions.  

### **Features:**
- **H-Bridge Configuration:** Full-bridge driver for bidirectional motor control.  
- **Integrated MOSFETs:** Reduces external component count.  
- **PWM Control:** Supports pulse-width modulation for speed control.  
- **Diagnostic Feedback:** Fault status output for system monitoring.  
- **Low-Power Sleep Mode:** Reduces quiescent current when inactive.  
- **Cross-Conduction Protection:** Prevents shoot-through current.
