Type
Function
Logic Input Bridge A Logic Input 1.
Logic Input Bridge A Logic Input 2.
Power Supply Bridge A Source Pin. This pin must be connected to Power
Ground directly or through a sensing power resistor.
Power Output Bridge A Output 1.
GND
Signal Ground terminals. In PowerDIP and SO packages,
these pins are also used for heat dissipation toward the
PCB.
Power Output Bridge B Output 1.
Power Supply Bridge B Source Pin. This pin must be connected to Power
Ground directly or through a sensing power resistor.
Logic Input Bridge B Logic Input 1.
Logic Input Bridge B Logic Input 2.
Logic Input ⁽⁶⁾
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.
Supply
Voltage
Bootstrap Voltage needed for driving the upper
PowerMOSFETs 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 VS_A.
Power Supply Bridge A Power Supply Voltage. It must be connected to
the supply voltage together with pin VS_B.
Power Output Bridge A Output 2.
Output
Charge Pump Oscillator Output.
Logic Input ⁽⁶⁾
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.
(6) Also connected at the output drain of the Overcurrent and Thermal protection MOSFET. Therefore, it has to be driven putting in series a
resistor with a value in the range of 2.2kΩ - 180KΩ, recommended 100kΩ
