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

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.
