PIN FUNCTIONS

Pin #

Name

Description

7

VIN

Input supply voltage. Decouple the VIN pin to ground with a minimum 100nF ceramic

capacitor. Additional bulk capacitance may be required.

11, 20

GND

Power ground.

6

VCLAMP

High side clamp. Connect the VCLAMP pin to a TVS or Zener diode then connect this

pin to VIN to clamp the leakage inductance spike.

4

SDI

Serial data input. The SDI pin has an internal pull-down resistor.

5

SCK

Serial clock input. The SCK pin has an internal pull-down resistor.

3

SDO

Serial data output. The SDO pin is an open-drain output that requires an external pull-up

resistor if used.

1

nSCS

Serial chip selection. The nSCS pin is an active low serial peripheral interface (SPI)

selector. nSCS has an internal pull-down resistor.

8

LATCH

Latch input. The LATCH pin has an internal pull-down resistor.

10

RESET

Device reset input. Drive the RESET pin active high to initialize the digital logic. RESET

has an internal pull-down resistor.

9

ENBL

Enable input. Drive the ENBL pin to logic low to disable the outputs; drive ENBL to logic

high to enable the outputs. The state of ENBL does not affect the serial interface. ENBL

has an internal pull-down resistor.

2

nFAULT

Fault indication. The nFAULT pin is an open-drain output that requires an external pull-

up resistor if used. nFAULT is driven low if a fault condition occurs.
