Bit | Field | Type | Default | Description |
---|---|---|---|---|
7 | LS_REF | R/W | 0b |
0b = VDS_OCP for the low-side MOSFET is measured across DLx to SLx 1b = VDS_OCP for the low-side MOSFET is measured across DLx to AGND (see Figure 37) |
6 | CSA_FET | R/W | 0b |
0b = Current sense amplifier positive input is SPx 1b = Current sense amplifier positive input is DLx (also automatically sets the LS_REF bit to 1b |
5-4 | CSA_GAIN_C | R/W | 10b |
00b = 5 V/V current sense amplifier gain 01b = 10 V/V current sense amplifier gain 10b = 20 V/V current sense amplifier gain 11b = 40 V/V current sense amplifier gain |
3-2 | CSA_GAIN_B | R/W | 10b |
00b = 5 V/V current sense amplifier gain 01b = 10 V/V current sense amplifier gain 10b = 20 V/V current sense amplifier gain 11b = 40 V/V current sense amplifier gain |
1-0 | CSA_GAIN_A | R/W | 10b |
00b = 5 V/V current sense amplifier gain 01b = 10 V/V current sense amplifier gain 10b = 20 V/V current sense amplifier gain 11b = 40 V/V current sense amplifier gain |
