PRODUCTION DATA
The device has two ACDRV pins to drive two sets of N-channel ACFET-RBFET, which select and manage the input power from two different input sources. A single GaN FET can be used to replace an ACFET-RBFET combination and will be treated the same as an ACFET-RBFET combination. In the POR sequence, the device detects if the protection FET(s) are populated based on if ACDRV pin is shorted to ground or not, and then updates the status register ACRB1_CONFIG_STAT or ACRB2_CONFIG_STAT to indicate the presence of AC protection FETs. If the external ACFET-RBFET or GaN FET is not populated in the schematic, then tie VAC to VBUS and connect ACDRV to GND. The device supports:
The power-up sequences for different applications are described in detail below.
