Introducing the L9958XP - Advanced Motor Driver from STMicroelectronics
Discover the power and precision of the L9958XP, a state-of-the-art motor driver designed by STMicroelectronics. This exceptional device is tailored for the automotive industry, providing a robust and efficient solution for managing small motors and actuators. The L9958XP is an ideal choice for applications that demand high reliability and performance, such as throttle control, wastegate, turbocharger, and EGR.
The L9958XP is a monolithic, H-bridge motor driver that operates on a supply voltage from 8V to 18V, making it versatile for various automotive applications. Its impressive features include a programmable peak current up to 5A, as well as a current sense output that allows for real-time monitoring of the motor current, ensuring optimal control and protection of the motor.
With an integrated charge pump, the L9958XP ensures constant gate drive supply voltage, even at low supply voltages, thus maintaining the H-bridge's high performance across the entire operating range. The device also provides diagnostic functions via a serial peripheral interface (SPI), which can alert the system in case of under-voltage, over-temperature, or short-circuit conditions, contributing to the overall safety and longevity of the motor control system.
The motor driver's PWM capability with frequencies up to 20kHz allows for silent operation, a critical feature in automotive environments where noise reduction is paramount. Moreover, the L9958XP's full-bridge output stage is designed to minimize power dissipation, thanks to its low RDS(on) values, making the device not only powerful but also energy-efficient.
STMicroelectronics has packaged the L9958XP in a PowerSSO-36, which provides excellent thermal performance and space-saving on the PCB. Whether you're designing an automotive application or looking for a reliable motor control solution, the L9958XP motor driver offers the perfect blend of power, precision, and protection.
Choose the L9958XP for your next project and experience the quality and performance that STMicroelectronics is known for.
