DC Motor Driver 2x15A Lite

SKU: DRI0018

The DC Motor Driver 2x15A Lite offers high-power motor control with dual H-bridge driver capabilities, supporting 4.8-27V input and 15A maximum output per channel. It includes advanced features like galvanic isolation to protect microcontrollers, dual current detection diagnostics, and safeguards against short circuit, overheating, and over-voltage. The driver accommodates up to 25 kHz PWM and interfaces with four digital IO, including two PWM outputs. Measuring 73×68×14mm, it is designed for applications requiring more than 15A per channel, cautioning against fast switching which might damage the board, and recommending lower PWM settings for higher rating motors. With detailed pinout information, the driver facilitates easy current sense and diagnosis for efficient motor operation.

    LA_IS, LB_IS, RA_IS & RB_IS is for current sense and diagnosis.

    In normal operation, the IS pin output a low level. In a fault condition, it will output a high level. The following code will show you how to do.

    • LA_IS and RA_IS is used for Motor1
    • LB_IS and RB_IS is used for Motor2
