Battery voltage (low) input

11

CS

Digital input with pull-up

Chip select with an internal pull-up resistor (SPI

Interface)

12

SCLK

Digital input

Clock signal (SPI Interface)

13

SDO

Digital output

Serial data input (SPI Interface)

14

DVSS

Supply pad

0V digital ground

15

DVDD

+3.3V digital supply

16

CHOP_CLK

Digital output

Chop clock used in High side measurements to

synchronize external chopper.

17

MEN

Digital output issued during the Standby Mode

(SBM) to signal the short duration of data sam-

pling. This signal is useful in the case of a High

Side Measurement application.

18

SDI

Digital input

Data signal (SPI Interface)

19

CLK

Digital I/O

By default this pin is the internal clock output which

can be used by a microcontroller. The internal

clock may also be disabled as an output by

programming Register 08. To use an external

Clock, Register 08 has to be programmed.

20

INT

Digital output

Active high Interrupt to indicate data is ready
