Open Drain
Output
Bridge A Overcurrent Detection and thermal protection pin.
An internal open drain transistor pulls to GND when
overcurrent on bridge A is detected or in case of thermal
protection.

GND GND Signal Ground terminals. In Power DIP and SO packages,
these pins are also used for heat dissipation toward the
PCB.

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 SENSE

Logic Input Bridge B Input 2
13 28 PROGCL
B
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.
