FAQs
What is BD9328EFJ?
The BD9328EFJ is a dual H-bridge motor driver IC designed by ROHM Semiconductor. It is specifically tailored for driving DC brushed motor applications, making it suitable for use in robotics, automotive systems, and consumer electronics.
How Does BD9328EFJ Work?
The BD9328EFJ works by providing bidirectional control of the motor voltage, allowing forward and reverse rotation of a DC brushed motor. It is capable of driving two motors independently, making it suitable for applications requiring precise motor control. The IC features built-in protection circuits to ensure safe and reliable operation of the connected motors.
How Many Pins does BD9328EFJ have and What are the Functions of the Pinout Configuration?
The BD9328EFJ is available in a 24-pin HSSOP (Heat Sink Small Outline Package) package. The pinout configuration includes:
- VCC: Motor supply voltage pin.
- VREF: Reference voltage input pin for controlling the motor output voltage.
- AIN1, AIN2: Inputs for controlling the direction and speed of motor 1.
- BIN1, BIN2: Inputs for controlling the direction and speed of motor 2.
- STBY1, STBY2: Standby control inputs for enabling or disabling the motor outputs.
- OUT1A, OUT1B: Outputs for driving motor 1.
- OUT2A, OUT2B: Outputs for driving motor 2.
- Other Pins: Pins for ground connection, fault flag outputs, and other control and protection functions.
What are the Pros and Cons of BD9328EFJ?
Pros:
