    Trouble when using BTN8982

    "I'm using BTN8982 with an arduino mega, and I did the exactly same circuit as shown in the datasheet. In my pcb, I use 4 chips, in 2 H-bridges.

    In the first H-bridge, one chip is working perfectly fine, the other one is always turned ON, doesn't matter the voltage i'm driving it. I measured the IN pin of the defective chip and it's always around 1.8v, regardless the voltage on the 10k resistor.

    In the second H-bridge, none of the chips are working, the output is always low, the IN pins are alwasy low, regardless of the voltage on the 10k resistor."

    Hello, could you please share the schematic of your circuit? I think we could help you more with it. For the moment, it looks like the devices are broken or the Arduino board is broken. Please check the impedence between different pins of the device to see if the device is broken(shorted).

    Same Problem

    I have the same problem here. I use the chip to make motor drivers for robots. Some of the boards I have these exactly same issue, in others, It works perfectly. All the boards I use for the same model of motor, and I use a standalone ATmega2560 (from Arduino Mega) in other board to control them.
