L6206Q

Pin connection

IN2B

Logic input

Bridge B input 2

PROGCLB

R pin

Bridge B overcurrent level programming. A resistor connected between

this pin and ground sets the programmable current limiting value for

bridge B. By connecting this pin to ground the maximum current is set.

This pin cannot be left unconnected.

ENB

Logic input

Bridge B enable. LOW logic level switches OFF all Power MOSFETs of

bridge B. If not used, it must be connected to +5 V.

VBOOT

Supply voltage

Bootstrap voltage needed for driving the upper Power MOSFETs of both

bridge A and bridge B.

22, 23

OUT2B

Power output

Bridge B output 2.

26, 27

VSB

Power supply

Bridge B power supply voltage. It must be connected to the supply

voltage together with pin VSA.

34, 35

VSA

Power supply

Bridge A power supply voltage. It must be connected to the supply

voltage together with pin VSB.

38, 39

OUT2A

Power output

Bridge A output 2.

VCP

Output

Charge pump oscillator output.

ENA

Logic input

Bridge A enable. LOW logic level switches OFF all Power MOSFETs of

bridge A. If not used, it must be connected to +5 V.

PROGCLA

R pin

Bridge A overcurrent level programming. A resistor connected between

this pin and ground sets the programmable current limiting value for

bridge A. By connecting this pin to ground, the maximum current is set.

This pin cannot be left unconnected.
