A2919
Dual Full-Bridge PWM Motor Driver
Description (continued)
The A2919 is supplied in a 24-pin surface-mountable SOICW with dissipation in the smallest possible construction. The A2919 is
heat sinkable tabs for improved power dissipation capabilities . available for operation from -20°C to 85°C, and are also available
This batwing construction provides for maximum package power on special order for operation to +125°C.
