Current Sense Mode
R/W
0 = Current sense with external resistor.
1 = Current transformer.

Chopper Enable
R/W
When chopper = 1, current-sense amplifier is configured as a chopper amplifier.
Otherwise, current-sense amplifier is continuous time amplifier.

Description
7–0
False UV Clamp
R/W
This register contains the false UV clamp settings. This can be programmed from 1.3 V to 2.1 V
when the nominal voltage is 2 V. Each LSB increases the UV Clamp setting by 3.1 mV.

Load Voltage Trim
R/W
This register contains the load voltage trim settings and is normally written to during the user
to set the output voltage.
Table 35. Register 1Ah, Sel CBD/SMBAlert1. Power-On Default From EEPROM Register 811Ah During Power-Up
Bit No.
Name
R/W
Description
This register allows the user to set the CBD/Alert pin when certain flag conditions occur. These
bits are set up in an OR function so that any one flag can set the CBD/Alert pin. This register is
used with Register 1Bh.
