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 compatible with TTL, DTL, and 5 V CMOS logic. Except
for a common supply voltage and thermal shutdown, the two drivers in
each package are completely 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 characterized by low power dissipation levels and maximum
efficiency. A PHASE input to each bridge determines load-current
direction.
Extensive circuit protection is provided on-chip. Both ground-
clamp and flyback diodes for each bridge are provided. A thermal
shutdown circuit disables the load drive if chip temperature rating
(package power dissipation) is exceeded. Internally-generated delays
provide crossover-current protection.
The UDN2998W is packaged in a 12-pin single in-line power-tab
package for high power capabilities. Driving either of the bridges at
the full 2 A dc rating requires the use of an external heat sink. The tab
is at ground potential and needs no insulation.
