CS8441YN8

PMIC - Motor Drivers, Controllers

The CS8441YN8 is a motor controller and driver-integrated monolithic circuit developed by California Micro Devices. It is used in many high-end applications including the automotive industry, medical imaging, and communication devices.

The CS8441YN8 provides power management, DC motor control, and current sensing in one package. With its low voltage drop, the circuit is designed to save energy by driving DC motors with minimal loss. It is also designed for low heat emission and low impedance, meaning it is well-suited for automotive and many other applications.

The CS8441YN8 features a current-limit input control and a regulated voltage output of up to 24V. The circuit also incorporates a thermal overload circuit with automatic thermal shut-off and temperature compensation capabilities. This circuit prevents excessive current from flowing through the integrated circuit, protecting it from being damaged or destroyed.

The CS8441YN8 is capable of controlling and driving up to four motors simultaneously, with a maximum motor speed of up to 2MHz. The integrated circuit also includes a PWM input comparator with hysterisis (hysteresis is a control system response in which an output responds to an input when that input passes outside of an acceptable range), allowing for continual motor speed control.

The circuit also includes a transient suppression circuit, which is designed to protect the integrated circuit from voltage spikes caused by electromagnetic interference (EMI). The transient suppression circuit filters out high-energy noise from the power supply, preventing damage to the integrated circuit.

The CS8441YN8 is also designed for easy electrical testing and programming. The integrated circuit includes self-test codes, which can be used to automatically test the circuit for proper operation. Additionally, the circuit allows for reprogramming, meaning that the device can be programed to a new mode, setting, or configuration for different applications.

The CS8441YN8 is an ideal choice for applications that need a reliable, high-performance motor controller and driver. The integrated circuit is designed for low heat emission levels and easy programming and testing using self-test codes, making it well-suited for many different applications.
