A3966
Description (continued)
Dual Full-Bridge PWM Motor Driver
each bridge, an ENABLE input, when held high, disables the output
drivers. Special power-up sequencing is not required. Internal circuit
protection includes thermal shutdown with hysteresis, ground-clamp
and flyback diodes, and crossover-current protection.
Selection Guide
The A3966 is supplied in a 16-lead plastic wide 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.
