Type

Function

Logic input Bridge B input 2

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.

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.

Supply voltage

Bootstrap voltage needed for driving the upper Power MOSFETs of both

bridge A and bridge B.

Power output Bridge B output 2.

Power supply

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

voltage together with pin VSA.

Power supply

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

voltage together with pin VSB.

Power output Bridge A output 2.

Output

Charge pump oscillator output.

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.

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.
