Part Number:DRV8870
Hi,
I am using DSPIC33EP512 MCU to control the PWM output of DRV8870. When set the duty cycle to any level between 1-100% to PWM control IN1 or IN2 of DRV8870, the output of Out1 or Out2 is not matching with the PWM i set. Ex: If i set it 100%, the output is around 28%. If I only control IN1 or IN2 as On or Off, the Out1 and Out2 voltage are as expected.
I am using CCS C compiler IDE version 5.064, and the control. With the same control i tested to PWM control a mosfet gate, and the duty cycle come out as expected.
