Description

1

SCLK

Serial Clock Input. The serial clock is used to clock data into and out of any register of the device.

2

DOUT

Serial Data Output. Data is clocked out on the falling edge of SCLK and is valid on the rising edge of SCLK.

3

DIN

Serial Data Input. Data to be loaded into the control registers of the part is provided on this input. Data is clocked

into the registers on the rising edge of SCLK.

4

CS

Chip Select Input. The device is enabled when this pin is low. The device is disabled when this pin is high.

5

INT

Overtemperature and Undertemperature Indicator. Logic output. When the device is powered up, this output is an

active low interrupt by default. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.

6

CT

Critical Overtemperature Indicator. Logic output. The default power-on polarity is active low. Open-drain

configuration. A pull-up resistor is required, typically 10 kΩ.

7

GND

Analog Ground. This pad must be connected directly to Pad 8 (digital ground).

8

GND

Digital Ground. This pad must be connected directly to Pad 7 (analog ground).

9

Analog Supply Voltage (2.7 V to 5.5 V). This pad must be connected directly to Pad 10 (digital supply voltage). The

supply should be decoupled with a 0.1 μF ceramic capacitor to GND.

10

Digital Supply Voltage (2.7 V to 5.5 V). This pad must be connected directly to Pad 9 (analog supply voltage). The

supply should be decoupled with a 0.1 μF ceramic capacitor to GND.
