designed to drive both windings of a bipolar stepper motor or

bidirectionally control two dc motors. Both bridges are capable of

sustaining 45 V and include internal pulse-width modulation (PWM)

control of the output current to 750 mA. The outputs have been opti-

mized for a low output saturation voltage drop (less than 1.8 V

total source plus sink at 500 mA).

mined by the user’s selection of a reference voltage and sensing

resistor. Two logic-level inputs select output current limits of 0, 33,

67, or 100% of the maximum level. A PHASE input to each bridge

determines load current direction.

protection against inductive transients. Internally generated delays

prevent cross-over currents when switching current direction. Special

power-up sequencing is not required. Thermal protection circuitry

disables the outputs if the chip temperature exceeds safe operating

limits.

The UDN2916B is supplied in a 24-pin dual in-line plastic batwing

package with a copper lead-frame and heat sinkable tabs for improved

power dissipation capabilities. The UDN2916EB is supplied in a 44-

lead power PLCC for surface mount applications. The UDN2916LB is

supplied in a 24-lead surface-mountable SOIC. Their batwing construc-

tion provides for maximum package power dissipation in the smallest

possible construction. The UDN2916B, UDN2916EB, and UDN2916LB

are available for operation from –20°C to 85°C. The UDQ2916B and

UDQ2916LB are available for operation from –40°C to 105°C. All

packages are lead (Pb) free, with 100% matte tin leadframe.
