Dual Full Bridge PWM Motor Driver

EN1 m o .c U 4 t e e h S a at .D w w w SENSE 1 PHASE 1 VREF 1 ENABLE 1 2 91 7 DUAL FULL-BRIDGE PWM MOTOR DRIVER The UDN2917EB motor driver is 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 1.5 A. For PWM current control, the maximum output current is determined 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. Active-low ENABLE inputs control the four drivers in each bridge. The bridges include both ground clamp and flyback diodes for 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 UDN2917EB is supplied in a 44-lead power PLCC for surfacemount applications. Its batwing construction provides for maximum package power dissipation in the smallest possible construction. The UDN2917EB is provided for operation over an ambient temperature range of -20°C to +85°C.
