LP876242-Q1: 30 DRV_EN of GPIO1

Hello123

Part Number: LP876242-Q1
Other Parts Discussed in Thread: AWR2243

In this pmic, it seems that only one GPIO (GPIO1)can be configured as DRV_EN . I am correct ? if we have more peripherals need to shut down by PMIC with the function of DRV_EN. How can we do ?it seems only one DRV_EN is not enough.

Hi Jin,

If you are using LP876242B0RQKRQ1 then only GPIO1 can be used as EN_DRV. This configuration has been designed for AWR2243 and in this use case only one devices state is controlled by the PMIC.

Niko
