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 Output 1.
Signal Ground terminals. In PowerDIP and SO packages,
these pins are also used for heat dissipation toward the
PCB.
Bridge B Output 1.
Bridge B Source Pin. This pin must be connected to Power
Ground directly or through a sensing power resistor.
Bridge B Logic Input 1.
Bridge B Logic Input 2.
Bridge B Enable. LOW logic level switches OFF all Power
MOSFETs of Bridge B. This pin is also connected to the
collector of the Overcurrent and Thermal Protection
transistor to implement over current protection.
If not used, it has to be connected to +5V through a
resistor.
Bootstrap Voltage needed for driving the upper
PowerMOSFETs 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.
Charge Pump Oscillator Output.
Bridge A Enable. LOW logic level switches OFF all Power
MOSFETs of Bridge A. This pin is also connected to the
collector of the Overcurrent and Thermal Protection
transistor to implement over current protection.
If not used, it has to be connected to +5V through a
resistor.
