FUNCTIONAL DEVICE OPERATION

LOGIC COMMANDS AND REGISTERS

SREG2_V[7]: Reference DAC MSB

1 = SREG2_V[7] on

0 = SREG2_V[7] off

SREG2_V[6]: Reference DAC Bit6

1 = SREG2_V[6] on

0 = SREG2_V[6] off

SREG2_V[5]: Reference DAC Bit5

1 = SREG2_V[5] on

0 = SREG2_V[5] off

SREG2_V[4]: Reference DAC Bit4

1 = SREG2_V[4] on

0 = SREG2_V[4] off

SREG2_V[3]: Reference DAC Bit3

1 = SREG2_V[3] on

0 = SREG2_V[3] off

SREG2_V[2]: Reference DAC Bit2

1 = SREG2_V[2] on

0 = SREG2_V[2] off

SREG2_V[1]: Reference DAC Bit1

1 = SREG2_V[1] on

0 = SREG2_V[1] off

SREG2_V[0]: Reference DAC LSB

1 = SREG2_V[0] on

0 = SREG2_V[0] off

Refer to Table 13, Output Voltage of SREG2 on page 21

for the correspondence between the output voltage and

SREG3_V[5]: Reference DAC MSB

1 = SREG3_V[5] on

0 = SREG3_V[5] off

SREG3_V[4]: Reference DAC Bit4

1 = SREG3_V[4] on

0 = SREG3_V[4] off

SREG3_V[3]: Reference DAC Bit3

1 = SREG3_V[3] on

0 = SREG3_V[3] off

SREG3_V[2] : Reference DAC Bit2

1 = SREG3_V[2] on

0 = SREG3_V[2] off

SREG3_V[1] : Reference DAC Bit1

1 = SREG3_V[1] on

0 = SREG3_V[1] off

SREG3_V[0]: Reference DAC LSB

1 = SREG3_V[0] on

0 = SREG3_V[0] off

CP Off: Charge Pump Control

1 = Charge Pump off

0 = Charge Pump on

EXTG On: VGATE_EXT Control *

1 = VGATE_EXT is low (GND level)

0 = VGATE_EXT is high (VG level)

EXTG On Register is assumed to use Pch FET as external

MOSFET.

If Nch FET will be used, Control logic should be inverted.

Refer to Table 14, Output Voltage of SREG3 on page 21
