DRV2624: Question of DRV2624 Power Up Sequence

Wayne Chen (ex FAE)

Part Number: DRV2624

Hi Sirs,

Would you pls advise if there is DRV2624 power up sequence specification? Any signal sequence customers should follow? (Ex: Power on/off sequence, How long I2C can send command after power on? Reset pin sequence?)

Thank you and Best regards,

Hi Wayne,

This device has very little requirements for power-up and power-down.
We have a suggested starting sequence in section 9.3.1. You need to wait 1ms after NRST power-up for I2C communication (I2C is disabled when NRST is low). The NRST pin can be turned on during that time or after. NRST and VDD can be turned on at the same time as well. For power-down, you can turn off VDD or pull NRST low to reach the low-power shutdown state.
