BIT BIT NAME DESCRIPTION
[15] EN_ICHG_PRESET Disable SEL_MORE_PRESET bits functions and its additional FDPM deglitch for minimizing IINDPM overshoot.
0: Disable
1: Enable (default at POR)
[14] 3L_TIME Three level adapter current limit feature time duration adjustment for 3L unlimited input current. Not recommend to change this on the fly when peak power mode is active.
0: 1ms (default at POR)
1: 3ms
[13:12] SEL_MORE_PRESET ICHG current regulation internal amplifier preset output value adjustment.
00: 0mV (default at POR)(Additional 160us deglitch time for FDPM enter add on FDPM_DEG)
01: 15mV(Additional 160us deglitch time for FDPM enter add on FDPM_DEG)
10: 30mV(Additional 640us deglitch time for FDPM enter add on FDPM_DEG)
11: 40mV(Additional 640us deglitch time for FDPM enter add on FDPM_DEG)
[11] EN_TURBO_FAST_TRANS Enable the ultra fast temporary turbo boost mode entry feature. This also activates the minimum turbo boost blank time (BOOST_EXIT_BLK) which prevents exiting turbo boost within 320us after FDPM_DEG. Setting to 0b decreases the minimum turbo boost time to either 30us (if adapter current stays below 750mA) or FDPM_FALL_DEG (if adapter current stays below FDPM_FALL but above 750mA).
0: Disable
1: Enable (default at POR)
[10] EN_CHARGE_FAST_TRANS Enable the ultra fast temporary ICHG fast recovery feature.
0: Disable
1: Enable (default at POR)
[9:8] TURBO_SPEED Turbo Boost mode startup RHP zero compensation adjustment.
00: Original speed no change (default at POR)
01: 15% speed increase
10: Reserved (similar to code 01b)
11: Reserved (similar to code 01b)
[7] GDRV_STR_EN Enable BUCK charger HS and LS gate drive strength. When enabled, it is recommended to include an RC low pass filter on ACP/ACN to improve IINDPM/PMON/IADP accuracy.
0: Disable
1: Enable (default at POR)
[6:5] AC_PLUG_EXIT_DEG Deglitch time from AC pluged in to charger exit battery only boost mode.
00: 25 ms
01: 3 ms(default at POR)
10: 2 ms
11: 1 ms
[4:2] Hybrid Power Boost Mode Entry Threshold
(FDPM_RISE)		 Fast DPM comparator threshold to enter hybrid power boost mode. The threshold is set as percentage to the input current limit. When peak power is not enabled, the input current limit is ILIM1, set in REG0x3F(). When the device is in TOVLD of peak power mode cycle, input current limit is ILIM2, and the threshold is 107% of ILIM2. For the rest of peak power mode cycle, input current limit is ILIM1.
