The Allegro Microsystems UDN2916EBTR-T is a dual full-bridge PWM motor driver designed for driving bipolar stepper motors or controlling two DC motors bidirectionally. It supports output sustaining voltages up to 45V and can handle a continuous output current of 750mA, with peak currents up to 1.0A.
This driver integrates pulse-width modulation (PWM) control for output current, allowing for precise motor control. It features internal clamp and flyback diodes for protection against inductive transients, and internal delays prevent crossover currents during direction switching. The outputs are optimized for low saturation voltage drop, less than 1.8V total at 500mA.
Designed for surface mount applications, the UDN2916EBTR-T comes in a 44-lead power PLCC package. It operates within a temperature range of -20°C to 85°C. The device includes internal thermal shutdown circuitry for protection against over-temperature conditions. Special power-up sequencing is not required.
This motor driver is similar to the Dual PBL3717 and UC3770. It is recommended for new applications to consider the A4970 as a substitution. Note that this device is discontinued and should not be purchased for new design applications.
