Application Field of LC898122AXA-VH

LC898122AXA-VH is a dual H-bridge motor driver, which is suitable for driving brushed DC motors and stepper motors in a wide range of applications. It is capable of controlling two different motors simultaneously or independently, with or without feedback. With its high accuracy and good performance, LC898122AXA-VH is an ideal fit for various industrial automation applications, like robots, 3D printers, automated guided vehicles, and so on.

LC898122AXA-VH also comes with many convenient features, such as over-current protection, under-voltage lockout, current decay control, and temperature protection. These features make it a perfect choice for applications that need reliable and accurate motor control. Furthermore, LC898122AXA-VH has a low on-resistance of 0.5Ω, which makes it ideal for driving large loads.

Working Principle of LC898122AXA-VH

LC898122AXA-VH is a dual H-bridge motor driver, which means two separate circuits are shared between two motors. The two separate circuits allow for separate power sources and enable independent, synchronized, or simultaneous control of two separate motors.

When LC898122AXA-VH receives an input signal from the external microcontroller, it will interpret the signal into the corresponding motor control commands. Depending on the command and the motor’s configuration, the H-bridge will use two pairs of PWM signals to control and regulate the motors, by providing different speed, direction, and torque.

In addition, LC898122AXA-VH supports a wide input voltage range, and enables power-on reset (POR) and brown-out reset (BOR). Moreover, with its temperature protection feature, the chip can detect and shutdown when the temperature is too high, to prevent damaging the motors and other components.

Conclusion

LC898122AXA-VH is a dual H-bridge motor driver, which can provide reliable motion control for a range of applications. It has many convenient features, such as over-current protection, under-voltage lockout, current decay control, and temperature protection. It is capable of controlling two different motors simultaneously or independently, with or without feedback. With its wide voltage range and low on-resistance, LC898122AXA-VH is an ideal fit for a variety of industrial automation applications.
