Signal ground terminals.
Bridge B overcurrent detection and thermal protection pin. An internal open
drain transistor pulls to GND when overcurrent on bridge B is detected or in
case of thermal protection.
Bridge B source pin. This pin must be connected to power ground directly or
through a sensing power resistor.
Bridge B input 1
Bridge B input 2
Bridge B overcurrent level programming. A resistor connected between this
pin and ground sets the programmable current limiting value for the bridge B.
By connecting this pin to ground the maximum current is set. This pin cannot
be left non-connected.
Bridge B enable. LOW logic level switches OFF all power MOSFETs of
bridge B.
If not used, it has to be connected to +5 V.
Bootstrap voltage needed for driving the upper power MOSFETs of both
bridge A and bridge B.
Bridge B power supply voltage. It must be connected to the supply voltage
together with pin VSA.
Bridge A power supply voltage. It must be connected to the supply voltage
together with pin VSB.
Charge pump oscillator output.
Bridge A enable. LOW logic level switches OFF all power MOSFETs of
bridge A.
If not used, it has to be connected to +5 V.
Bridge A overcurrent level programming. A resistor connected between this
pin and ground sets the programmable current limiting value for the bridge A.
By connecting this pin to ground the maximum current is set. This pin cannot
be left non-connected.
