Bridge B source pin. This pin must be connected to power ground
through a sensing power resistor.
Bridge B input 1
Bridge B input 2
Bridge B current controller reference voltage. Do not leave this pin open
or connect to GND.
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 overcurrent protection. If
not used, it must be connected to +5 V through a resistor.
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 VSA.
Bridge A power supply voltage. It must be connected to the supply
voltage together with pin VSB.
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 transistor to implement overcurrent protection. If not used, it must be
connected to +5 V through a resistor. Thermal protection
Bridge A current controller reference voltage. Do not leave this pin open
or connect to GND.
1. Also connected at the output drain of the overcurrent and thermal protection MOSFET. Therefore, it must be driven putting
in series a resistor with a value in the range of 2.2 k - 180 k, recommended 100 k.
