3.5 EN / PB / VSENSE Settings

The EN/PB/VSENSE pin is used to enable or disable the PMIC. This pin can be configured in one of three ways: EN, PB or VSENSE. The table below shows the default configuration on for this TRM which is linked to a specific part number. Please note, if the FSD (First supply detection) feature is enabled, the device goes from "No Power" to "Active" state, executing the power-up sequence as soon as the voltage on VSYS is above the POR threshold. In this scenario, the EN/PB/VSENSE pin is ignored ONLY during the first power-up.

Table 3-10 EN / PB / VSENSE Settings
Register Address Field Name Value Description
Pin Config 0x20 EN_PB_VSENSE_CONFIG 0x0 Device Enable Configuration
ON Deglitch 0x20 EN_PB_VSENSE_DEGL 0x0 short (typ: 120us for EN/VSENSE and 200ms for PB)
First Supply Detection 0x20 PU_ON_FSD 0x0 First Supply Detection (FSD) Disabled.
Note: The deglitch configured on register field "EN_PB_VSENSE_DEGL" is for the ON request. The deglitch for the OFF request is not configurable. The parameters that are not configurable can be found in the Specifications section of the device data sheet.
