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.
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/EB/LB are available for opera-
tion from -40°C to +85°C. To order, change the prefix from 'UDN' to
'UDQ'. These devices are also available on special order for operation
to +105°C. The B and LB packages are available in a lead (Pb) free
version, with 100% matte tin leadframe.
