TPS92630-Q1: Reverse PWM signal

Part Number: TPS92630-Q1

Hi team,

This is FAE Jimmy support automotive application.

I have a question that since MCU is end-customer and my client is charge of designing LED part. the situation is that they would like to use MUC's GPIO to control LED Driver's PWM but the GPIO from MCU is reverse logic. it mean that when duty = 100% the LED driver can't light up. I know that change software is the easiest way to fix this situation but MCU is end-customer that my client  can't change. at this situation do we have negative triggered PWM LED driver? otherwise I think we only can add reverser at PWM. 

if you have any idea please let me know. thanks

BR,

Jimmy

  • Hi Jimmy,

    We don't have a negative triggered PWM LED driver. Yes, the customer needs to reverse the PWM signal via external components.

    In addition, what is the requirements of PWM frequency and duty cycle?
