The L9958SB is a powerful motor controller developed by STMicroelectronics. The L9958SB combines the latest PMIC technology with advanced motor control technologies to provide a cost effective, reliable and high performance solution for many motor control applications.

The L9958SB is designed to be used as a motor controller in a wide variety of applications, ranging from small and medium electric motors to large industrial servo motors. It provides integrated control features that enable the user to optimize the system\'s performance, such as an onboard power supply up to 18 V, support for pulse width modulation (PWM), Integrated current limitation, and an In-Circuit serial programming (ICSP) interface.

The L9958SB’s working principle is based on the use of Phase Locked Loop (PLL) technology which is commonly used in variable speed drives and electric motor controllers. The PLL control loop adjusts the motor speed according to a specific reference and is set to a predetermined range according to the application. The L9958SB motor controller is then capable of determining the motor speed and controlling the output power by adjusting the motor power supply, current and voltage levels.

The L9958SB is a highly integrated motor controller and provides PWM output frequencies up to 400 kHz. This allows for a wide range of motor speeds for different applications, including motors with varying inrush currents and power demands. Additionally, the L9958SB provides a wide range of features such as Channel Pulse-Width Modulation (PWM), Constant Voltage or Constant Current output, dynamically adjustable power levels, integrated current limitation, and advanced fail-safe protection functions, allowing the user to control their motor system with precision and confidence.

The L9958SB is a great solution for applications where precise control and high performance are necessary, such as in automotive, industrial automation and robotic systems. Additionally, the chip’s integrated features minimize installation time, minimize external components and minimize board space, making it an economical choice for applications where power or performance is of primary importance.

The L9958SB motor controllers are widely used in applications such as electric scooters, power tools, home appliances, pumps, compressors, robotic actuators and industrial automation systems. With its advanced features and reliable performance, the L9958SB is an ideal choice for a wide range of motor control applications.
