Dear Specialists:

I have some questions about the TPS65381A-Q1.

1. I have used the" SAFETY_FUNC_CFG Register" to put the chip into a voltage lock state .But how to shut down the TPS65381 when TPS65381 is in the power-latched status?

2. The TPS65381 write update "SAFETY_FUNC_CFG Register"only occur in the DIAGNOSTIC state, so how to enter diagnostic mode when TPS65381 is in the power-latched status?

Thank you,

Zhao

HI Zhao,

You should be able to put the device in standby mode by issuing the WR_CAN_STBY command. This command can be issue in any state of the device.

Please let me know is this answers your question.
