LC898300XA-MH is a pre-driver IC product of On-semi company. It is a sample based motor driver peripheral IC. It is widely used in motor products such as printers, copiers, HDD and VCM. Its working principle is to sample and hold the input current, voltage and position of the motor, and then convert these signals into digital signals, and then convert them into digital signals for control. The application field of LC898300XA-MH covers various fields such as printers, copiers, HDD heads and VCM, with high precision control, high efficiency and uniform movement.

LC898300XA-MH has the function of built-in channel power driver buffer, and the peripheral circuit is integrated in a single chip. The built-in drive buffer circuit can support the output current of up to 2A. It also has the function of built-in sample and hold circuit, and it can be externally connected with an external wide band active filter circuit capable of supporting up to 30V, to get higher acquisition speed and hold accuracy.

The internal timing circuit of this product is based on a single-phase clock that can support a frequency range of 50KHz - 150KHz. It has the function of automatic soft switching and the built-in soft switching circuit can reduce the peak current flowing through the power driving transistor. In addition, the built-in current sensing circuit can accurately detect the driving current.

LC898300XA-MH also has other features such as automatic idle state, handshaking protocol and serial port access. It supports UART, SPI and I2C serial communication interfaces. With these features, it can easily realize multiple system functions such as serial communication port control and motors speed braking. With advanced control system design and production, it can ensure the accuracy and stability of its movement.

The most remarkable feature of the LC898300XA-MH is its integrated Smart ID detection and temperature sensing warning circuit. When the temperature of the motor exceeds the fixed temperature, an accurate warning will be triggered to alert the user that the motor needs to be stopped immediately. In addition, the built-in ambient light sensor can control the speed and brightness of the motor, making it more stable and accurate.

Overall, the LC898300XA-MH is a perfect example of a modern motor controller. It is a highly integrated, high performance motor driver IC with advanced features like sample and hold, current sensing, and internal timing circuits. With its wide application fields and highly precise working principle, it can support the motorized application of different types of products. With its advanced temperature sensing warning circuit, it provides customers with more reliable performance and greater safety.
