UDN2998 Datasheet | Allegro MicroSystems

DUAL FULL-BRIDGE MOTOR DRIVER As an interface between low-level logic and solenoids, dc (brush) motors, or stepper motors, the UDN2998W dual full-bridge driver will operate inductive loads up to 50 V with continuous output currents of up to 2 A per bridge or peak (start-up) currents to 3 A. The control inputs are patible with TTL, DTL, and 5 V CMOS logic. Except for a mon supply voltage and thermal shutdown, the two drivers in each package are pletely independent. For external PWM control, an Output Enable for each bridge circuit is provided and the sink driver emitters are pinned out for connection to external current-sensing resistors. The chopper drive mode is...
