A3968
Description (continued)
of a bridge, the braking function is enabled. In brake mode, both
source drivers are turned off and both sink drivers are turned on,
thereby dynamically braking the motor. When a logic high is applied
to both INPUTs of a bridge, all output drivers are disabled.
Special power-up sequencing is not required. Internal circuit
protection includes thermal shutdown with hysteresis, ground-clamp

and flyback diodes, and crossover-current protection.
The A3968 is supplied in a 16-lead plastic SOIC with two pins
internally fused to the die pad for enhanced thermal dissipation. These
pins are at ground potential and need no electrical isolation. The
device is lead (Pb) free, with 100% matte tin leadframe plating.
