9.3.5.3 Single Input with ACFET1
In this scenario, ACFET1 without RBFET1 is populated, but ACFET2-RBFET2 is not. VAC2 is short to VBUS and ACDRV2 is pulled down to ground. The table below summarizes the VAC1/ VAC2, ACDRV1/ACDRV2 connection, register control, and status functions. Use VAC1 for single input configuration.
Table 9-2 Single Input with Single
ACFET1
| INPUT CONFIGURATION | SINGLE INPUT |
|---|---|
| External FET connection | ACFET1, no ACFET2-RBFET2 |
| Input pin connection | VAC1 connected to input source VAC2 short to VBUS |
| ACDRV pin connection | ACDRV1 active ACDRV2 tie to ground |
| ACDRV1_STAT | 1: ACDRV1 is ON 0: ACDRV1 is OFF |
| ACDRV2_STAT | 0 |
| DIS_ACDRV_BOTH | 0: Allow ACDRV1 to turn on if the conditions of ACDRV turn on
are met. 1: Force ACDRV1 OFF |
| ACRB1_CONFIG_STAT | 1 |
| ACRB2_CONFIG_STAT | 0 |
| EN_HIZ | 0: Allow ACDRV1 to turn on if the conditions of ACDRV turn on
are met. 1: Force ACDRV1 OFF |
