The L6226PD from STMicroelectronics is a high-performance dual full-bridge driver that is designed to drive bipolar stepper motors or bidirectional control of two DC motors. Integrated within a PowerSO-36 package, this IC is capable of delivering up to 1 A per channel with an operating voltage range from 8 V to 52 V, making it suitable for a wide array of industrial and consumer applications.
Featuring low ON resistance, the L6226PD ensures high efficiency and better thermal performance. Its DMOS output stages incorporate synchronous rectification, which further improves power dissipation during PWM operation. The device is also equipped with a non-dissipative overcurrent protection on the high side power MOSFETs and thermal shutdown to ensure the safety and durability of your application.
One of the key benefits of the L6226PD is its cross-conduction protection, which prevents accidental simultaneous conduction of the transistors in a half-bridge. This feature is essential for preventing potential hardware damage. Additionally, the device provides a full set of diagnostics via a non-dissipative current sense, overcurrent, and thermal shutdown with hysteresis.
The L6226PD is easy to implement in a circuit, thanks to its simple logic control for each bridge. It is compatible with standard microcontroller interfaces, and its mixed bipolar CMOS DMOS (BCD) technology allows the integration of analog features and power stages on the same chip, reducing the complexity and footprint of the overall solution.
With its robust design and comprehensive feature set, the L6226PD is an ideal solution for applications that require reliable and efficient motor control, such as office automation, factory automation, vending machines, and many more. Whether you're driving a small stepper motor in a precision positioning system or controlling the bidirectional movement of a DC motor, the L6226PD offers a compact, powerful, and versatile solution.
