3) POWER OFF (POF) (R02H)
After the Power OFF command, the driver will be powered OFF. Refer to the POWER
MANAGEMENT section for the sequence.
This command will turn off booster, controller, source driver, gate driver, VCOM, and temperature
sensor, but register data will be kept until VDD turned OFF or Deep Sleep Mode.
Source/Gate/Border/VCOM will be released to floating.
4) POWER OFF SEQUENCE SETTING (PFS) (R03 H)
T_VDS_OFF[1:0]:
Source to gate power off interval time.
00b: 1 frame (Default) 01b: 2 frames 10b: 3 frames 11b: 4 frame
5) POWER ON (PON) (REGISTER: R04H)
After the Power ON command, the driver will be powered ON. Refer to the POWER
MANAGEMENT section for the sequence.
This command will turn on booster, controller, regulators, and temperature sensor will be activated
for one-time sensing before enabling booster. When all voltages are ready, the BUSY_N signal will
return to high.
6) BOOSTER SOFT START (BTST) (R06H)
BT_PHA[7:6]: Soft start period of phase A.
00b: 10mS 01b: 20mS 10b: 30mS 11b: 40mS
BT_PHA[5:3]: Driving strength of phase A
000b: strength 1 001b: strength 2 010b: strength 3 011b: strength 4
100b: strength 5 101b: strength 6 110b: strength 7 111b: strength 8 (strongest)
BT_PHA[2:0]: Minimum OFF time setting of GDR in phase A
000b: 0.27uS 001b: 0.34uS 010b: 0.40uS 011b: 0.54uS
100b: 0.80uS 101b: 1.54uS 110b: 3.34uS 111b: 6.58uS
BT_PHB[7:6]: Soft start period of phase B.
00b: 10mS 01b: 20mS 10b: 30mS 11b: 40mS
