Pin connection

Table 5. Pin description

Pin

Type

Function

VBOOT Power supply Bootstrap voltage needed for driving the upper power MOSFETs.

VCP

Output Charge pump oscillator output.

DIAG-EN

Logic

output/input

Double function: chip Enable as input and Overcurrent/Over-temperature

indication as output.

LOW logic level switches OFF all Power MOSFETs, putting the power

stages in high impedance status.

An internal open drain transistor pulls to GND the pin when an overcurrent

on one of the High Side MOSFETs is detected or during Thermal

Protection.

IN1

Logic input Logic input half bridge 1.

EN1 Logic input Enable input half bridge 1.

IN2

Logic input Logic input half bridge 2.

EN2 Logic input Enable input half bridge 2.

IN3

Logic input Logic input half bridge 3.

EN3 Logic input Enable input half bridge 3.

CP- Analog input Inverting input of internal comparator.

CP+ Analog input Non-Inverting input of internal comparator.

CPOUT

SENSE3

Output

Open-drain output of internal comparator.

Half bridge 3 source pin. This pin must be connected to power ground

through a sensing power resistor.

OUT3

VSB

Power output Output half bridge 3.

Power supply

Half bridge 3 power supply voltage. it must be connected to the supply

voltage together with pin VSA.

SENSE2

Half bridge 2 source pin. This pin must be connected to power ground

through a sensing power resistor.

OUT2 Power output Output half bridge 2.

SENSE1

Half bridge 1 source pin. This pin must be connected to power ground

through a sensing power resistor.

OUT1 Power output Output half bridge 1.

VSA

Power supply

Half bridge 1 and half bridge 2 power supply voltage. It must be connected

to the supply voltage together with pin VSB.

GND

Ground Ground terminal.
