Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7-6 | Reserved | R | 0h | Reserved |
5-4 | INCAP_QCHG[1:0] | R/W | 0h | The duratiion of the quick-charge for the external AC-coupling capacitor is set using an internal series impedance of 800 Ω.
0d = INxP, INxM quick-charge duration of 2.5 ms (typical) 1d = INxP, INxM quick-charge duration of 12.5 ms (typical) 2d = INxP, INxM quick-charge duration of 25 ms (typical) 3d = INxP, INxM quick-charge duration of 50 ms (typical) |
3-2 | SHDNZ_CFG[1:0] | R/W | 1h | Shutdown configuration.
0d = DREG is powered down immediately after SHDNZ asserts 1d = DREG remains active to enable a clean shut down until a time-out is reached; after the time-out period, DREG is forced to power off 2d = DREG remains active until the device cleanly shuts down 3d = Reserved |
1-0 | DREG_KA_TIME[1:0] | R/W | 1h | These bits set how long DREG remains active after SHDNZ asserts.
0d = DREG remains active for 30 ms (typical) 1d = DREG remains active for 25 ms (typical) 2d = DREG remains active for 10 ms (typical) 3d = DREG remains active for 5 ms (typical) |
