CSNS

Output

Output Current

This pin reports an analog value proportional to the designated HS[0:3] output

Monitoring

current or the temperature of the GND flag (pin 14). It is used externally to

generate a ground-referenced voltage for the microcontroller (MCU) . Current

recopy and temperature feedback is SPI programmable.

2

IN0

Input

Direct Inputs

Each direct input controls the device mode. The IN[0 : 3] high side input pins

3

IN1

are used to directly control HS0 : HS3 high side output pins.

5

IN2

The PWM frequency can be generated from IN0 pin to PWM module in case

6

IN3

of external clock is set.

7

FS

Output

Fault Status

This pin is an open drain configured output requiring an external pull-up

(Active Low)

resistor to VDD for fault reporting.

8

WAKE

Input

Wake

This input pin controls the device mode.

9

RST

Input

Reset

This input pin is used to initialize the device configuration and fault registers,

as well as place the device in a low-current Sleep mode.

CS

Input

11

SCLK

Input

Chip Select

(Active Low)

Serial Clock

This input pin is connected to a chip select output of a master microcontroller

(MCU).

This input pin is connected to the MCU providing the required bit shift clock for

SPI communication.

12

SI

Input

Serial Input

This pin is a command data input pin connected to the SPI serial data output

of the MCU or to the SO pin of the previous device of a daisy-chain of devices.

13

VDD

Power Digital Drain Voltage This pin is an external voltage input pin used to supply power interfaces to the

SPI bus.
