Bit | Field | Default | Description |
---|---|---|---|
2 | SFMODE_SLEEP | 0 | To conserve power in SLEEP mode, the DSG FET driver may be configured to enter source-follower mode. This is normally only used when Settings:FET:FET Options[SLEEPCHG] is set to zero. When current is detected by the CC2 Wake Comparator, source-follower mode is disabled and the FET driver operates normally. Source-follower mode is also disabled when SLEEP mode is exited via other means. 0 = Source-follower mode is not enabled on the DSG FET driver 1 = Source-follower mode is enabled on the DSG FET driver while in SLEEP mode |
1 | LVEN | 0 | This bit selects the charge pump overdrive level. 0 = Charge pump high overdrive level (11 V) is selected 1 = Charge pump low overdrive level (5.5 V) is selected |
0 | CPEN | 1 | This bit enables or disables the charge pumps for the FET drivers. If FET drivers are not to be used at all, Settings:FET:FET Options[FET_CTRL_EN] should also be set to zero. 0 = Charge pumps for FET drivers are disabled 1 = Charge pumps for FET drivers are enabled |
