TPS65917-Q1: Control TPS65917-Q1 power sequence

Part Number: TPS65917-Q1

Hi,

The customer cannot modify the OTP registers, they are fixed once they leave the TI factory. But can customer use a additional MCU to control TPS65917-Q1 power sequence by SPI/I2C?

Best Regards,

Rock Su

  • Hi Rock,

    The sequencing cannot be changed by SPI/I2C. The power-up and power-down sequence is fixed. Once the device is powered up to the ACTIVE state, an external MCU can change the voltage settings, or enable/disable rails as needed.
