TPS2H160-Q1: Are INx pins are PWM compatible or can we control the OUTx current through INx pins

Part Number: TPS2H160-Q1

Hi Team,

We are using TPS2H160BQPWPRQ1 in our project and I want to information regarding the INx pins.

1. Can we feed PWM inputs to the INx pins and directly control the OUTx current?

2. Is there any fault indication when there is Short to battery or Short to GND condition?

Please support.

    Hello, 

    1. Please check out this FAQ which goes over what to consider when PWMing High side switches. The same applies for the TPS2H160-Q1
    2. Fault indication:
      1. Section 8.3.6.3 Short-to-Battery Detection discusses how to detect a short-to battery condition. Please let me know if you have any further questions. 
      2. Short to GND protection is provided via the current limit. When overcurrent occurs, the device improves system reliability by clamping the inrush current effectively. For the B version of the device, the fault can be known based on the Current-sense analog output. For the A version, the fault pin is pulled low to disclose a fault has occurred. Once the device heats up to the thermal shutdown threshold, the device will disable. 

    Best Regards,
