The NXP USA Inc. MC34921AER2 is a unipolar motor driver featuring a fully integrated control and power stage. This component utilizes Power MOSFET technology and is housed in a 64-LQFP-EP (10x10) package suitable for surface mounting. Designed for brushed DC and unipolar stepper motor applications, it provides an output current capability of 1.5A, with peak currents up to 4.5A. The device operates from a supply voltage range of 4.8V to 5.2V and supports load voltages from 0V to 38V. Its output configuration includes four half-bridge drivers, two high-side drivers, and one low-side driver. The MC34921AER2 is engineered for general-purpose applications and operates within an ambient temperature range of 0°C to 150°C. It communicates via a serial interface.
