Introduction
BD6221F-E2 Protected H-Bridge DC Brushed Motor Driver
BD6221F-E2 is a protected H-bridge DC brushed motor driver designed for small portable, household, and automotive micro motors.
Core Functions
- Monolithic H-bridge driver IC dedicated to DC brush motors, integrated with four power MOSFETs to form a complete H-bridge circuit
- Supports bidirectional rotation control of DC motors via two logic-level input pins, enabling forward rotation, reverse rotation, brake stop, and coast stop modes
- Built-in multiple protection circuits including overcurrent protection, thermal shutdown protection, and under-voltage lockout (UVLO) protection to prevent chip and motor damage
- Low on-resistance power transistors reduce conduction loss, enabling high-efficiency motor driving with minimal heat generation
- Wide operating supply voltage range adapts to various battery-powered and small industrial power supply scenarios
- Simple peripheral circuit design requiring minimal external passive components for complete motor drive setup
Typical Applications
- Small household appliances: electric toothbrushes, massagers, small water pumps, mini fans
- Consumer portable electronics: handheld beauty devices, toy DC motors, portable vacuum cleaners
- Office miniature equipment: mini cooling fans, small paper feed motors
- Automotive small actuators: car rearview mirror adjustment motors, car door lock micro-motors
- Industrial miniature actuators: miniature conveying rollers, small valve drive motors
