Bridge A Logic Input 1.
Bridge A Logic Input 2.
Bridge A Source Pin. This pin must be connected to Power
Ground directly or through a sensing power resistor.
Bridge A Overcurrent Detection and thermal protection pin.
An internal open drain transistor pulls to GND when
overcurrent on bridge A is detected or in case of thermal
protection.
Bridge A Output 1.
Signal Ground terminals. In Power DIP and SO packages,
these pins are also used for heat dissipation toward the
PCB.
Bridge B Output 1.
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 +5V.
Bootstrap Voltage needed for driving the upper Power
MOSFETs of both Bridge A and Bridge B.
Bridge B Output 2.
Bridge B Power Supply Voltage. It must be connected to
the supply voltage together with pin VS
Bridge A Power Supply Voltage. It must be connected to
the supply voltage together with pin VS
Bridge A Output 2.
