Name

Description

SO

VFQFPN

1

33

LGATE1

Channel 1 LS driver output.

A little series resistor helps in reducing device-dissipated power.

2

34

VCCDR

LS drivers supply: it can be varied from 5V to 12V buses.

Filter locally with at least 1

µF ceramic cap vs. PGND.

3

35

PHASE1

Channel 1 HS driver return path. It must be connected to the HS1 mosfet source

and provides the return path for the HS driver of channel 1.

4

36

UGATE1

Channel 1 HS driver output.

A little series resistor helps in reducing device-dissipated power.

5

2

BOOT1

Channel 1 HS driver supply. This pin supplies the relative high side driver.

Connect through a capacitor (100nF typ.) to the PHASE1 pin and through a diode

to VCC (cathode vs. boot).

6

4

VCC

Device supply voltage. The operative supply voltage is 12V ±10%.

Filter with 1

µF (Typ.) capacitor vs. GND.

7

5,6

SGND

All the internal references are referred to this pin. Connect it to the PCB signal

ground.

8

7

COMP

This pin is connected to the error amplifier output and is used to compensate the

control feedback loop.

9

8

FB

This pin is connected to the error amplifier inverting input and is used to

compensate the control feedback loop.
