The LM5100MX/NOPB is a Monolithic H-Bridge Gate Driver IC for Automotive and Industrial Motor Control, providing an ideal solution for customers needing to drive 3-phase PMBLDC and Stepper Motors. It provides a reliable way to manage a current loop, control a 3-phase motor, and handle the inrush current of motors. With an internal pre-driver and high-side/low-side driver, it is able to increase efficiency and minimize current limiting on the H-bridge while driving PMBLDC and Stepper Motors.

The LM5100MX/NOPB is designed with a wide operating temperature range between -40°C and 150°C, which makes it suitable for use in harsh environments. It also has a low-noise circulating current mode (CPM) control, with adjustable current protection levels. This allows users to adjust the protection level according to their specific motor characteristics and regulates the speed of the motor.

This Gate Driver IC is also equipped with Over temperature protection (OTP) which detects when the IC has exceeded its temperature limit, indicating a fault in the system and deactivating it immediately. Additionally, the LM5100MX/NOPB offers a wide range of protection features which help protect the internal components of the device and the system against over current, under-voltage, and over-voltage events. It also provides a high-side driver with a pre-driver that can control both the on-state and off-state.

The LM5100MX/NOPB has a wide range of applications ranging from automotive, industrial, industrial motor control, H-bridge motor control, to various other motor control applications. The Gate Driver IC is designed to support a wide range of motors, making it an ideal option for motor control applications. It is also designed to provide enhanced safety features, along with low power consumption and reduced maintenance costs.

The working principle of the LM5100MX/NOPB is simple yet effective. The device contains two power FETs and two output windings. When a voltage is applied to the output windings, the FETs are triggered, resulting in an electric current flow in the winding coil. This current induces an opposing voltage in the winding coil, which in turn causes the FETs to turn on and off in a rapid cycle. This rapid on and off cycle creates an oscillating current, which results in the generation of torque by the motor.

The LM5100MX/NOPB is an ideal choice for those who need a reliable and affordable solution to manage current loops, control a 3-phase motor, and handle the inrush current of motors. Its wide operating temperature range, low-noise circulation current mode, OTP protection, wide range of protection features, and low power consumption make it an ideal choice for any motor control application.
