The UDN2916LB is a versatile dual full-bridge PWM motor driver IC manufactured by Allegro Microsystems. It is engineered to drive both windings of a bipolar stepper motor or to control two DC motors bidirectionally. The device supports a continuous output current of up to 750 mA and can sustain output voltages of 45 V.
Key features include internal pulse-width modulation (PWM) current control, optimized low output saturation voltage, and internal clamp and flyback diodes for protection against inductive transients. Thermal protection circuitry is integrated to disable outputs if the chip temperature exceeds safe operating limits. Special power-up sequencing is not required.
This motor driver is supplied in a 24-lead surface-mountable SOIC package, making it suitable for space-constrained applications. It operates within a temperature range of -20°C to 85°C and is designed for general-purpose applications requiring precise motor control.
The UDN2916LB is similar to the Dual PBL3717 and UC3770, offering a robust solution for various motor control needs.
