Definition

1

CSNS

Output

Output Current/

This pin either outputs a current proportional to the channel’s output current or

Temperature

a voltage proportional to the temperature of the GND pin (pin 14). Selection

Monitoring

between current and temperature sensing, as well as setting the current

sensing sensitivity, are performed through the SPI interface. An external pull-

down resistor must be connected between CSNS and GND.

2

IN0

Input

Direct Inputs

The IN[0 : 1] input pins are used to directly control the switching state of both

3

IN1

switches and consequently the voltage on the HS0 : HS1 output pins. The pins

are connected to GND by internal pull-down resistors

4

FSOB

Output

Fail-safe Output FSOB is asserted (active-low) upon entering Fail-safe mode (see Functional

(Active Low)

Description) This open-drain output requires an external pull-up resistor to

VPWR

5

CONF0

Input

Configuration Input The CONF[0:1] input pins are used to select the appropriate overcurrent

6

CONF1

detection profile (bulb /DC motor) for each of both channels. CONF requires a

pull-down resistor to GND.

7

FSB

Output

Fault Status

This open-drain output pin (external pull-up resistor to VDD is required) is set

(Active Low)

when the device enters Fault mode (see Fault Mode)

8

CLOCK

Input

PWM Clock

The clock input gives the time-base when the device is operated in external

clock/internal PWM mode.

This pin has an internal pull-down current source.

9

RSTB

Input

Reset

This input pin is used to initialize the device’s configuration - and fault registers.

Reset puts the device in Sleep mode (low current consumption) provided it is

not stimulated by direct input signals.This pin is connected to GND by an

internal pull-down resistor.

10

CSB

Input

Chip Select

(Active Low)

This input pin is connected to the SPI chip-select output of an external micro-

controller. CSB is internally pulled up to VDD by a current source IUP.
