Description and Introduction

Single High-Side Switch (4.0 m?), PWM clock up to 60kHz The MC33981BPNA is a monolithic H-Bridge Power IC manufactured by NXP Semiconductors (formerly Freescale Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Operating Voltage Range:** 5.5V to 28V  
- **Output Current:** Up to 5A (continuous)  
- **Peak Output Current:** Up to 6.5A  
- **On-Resistance (RDS(on)):** Typically 150mΩ (per switch)  
- **PWM Frequency:** Up to 20kHz  
- **Sleep Mode Current:** <10µA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 32-pin QFN (5x5mm)  

### **Descriptions:**
- Designed for automotive and industrial applications.  
- Integrates an H-Bridge driver for bidirectional DC motor control.  
- Includes protection features such as overcurrent, overtemperature, and undervoltage lockout.  
- Supports PWM (Pulse Width Modulation) for speed control.  

### **Features:**
- **Integrated H-Bridge:** Allows bidirectional motor control.  
- **Protection Circuits:**  
  - Overcurrent protection (OCP)  
  - Overtemperature shutdown (TSD)  
  - Undervoltage lockout (UVLO)  
- **Diagnostic Feedback:** Fault status reporting via dedicated pins.  
- **Low-Power Sleep Mode:** Reduces power consumption when inactive.  
- **PWM-Compatible Inputs:** Supports external PWM control for speed regulation.  
- **Automotive-Grade:** AEC-Q100 qualified for harsh environments.  

This IC is commonly used in automotive applications such as power seat modules, window lift systems, and other motor control systems.
