9 24 OCDB
Open drain
output
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.
10 25 SENSEB
Power
supply
Bridge B source pin. This pin must be
connected to power ground directly or
through a sensing power resistor.
11 26 IN1B Logic input Bridge B input 1
12 27 IN2B Logic input Bridge B input 2
13 28 PROGCLB R pin
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.
14 29 ENB Logic input
Bridge B enable. LOW logic level switches
OFF all Power MOSFETs of bridge B. If not
used, it has to be connected to +5V.
15 30 VBOOT
Supply
voltage
Bootstrap voltage needed for driving the
upper Power MOSFETs of both bridge A
and bridge B.
16 32 OUT2B
Power
output
Bridge B output 2.
17 33 VSB
Power
supply
Bridge B power supply voltage. it must be
connected to the supply voltage together
with pin VSA.
20 4 VSA
Power
supply
Bridge A power supply voltage. it must be
connected to the supply voltage together
with pin VSB.
21 5 OUT2A
Power
output
Bridge A output 2.
22 7 VCP Output Charge pump oscillator output.
