PMIC - Motors Drivers, Controllers

The L9942XP1 IC is an integrated circuit (IC) IC specifically designed to control brushless DC (BLDC) and brushed DC motors. This controller combines the functions of an H-Bridge for driving the motor plus various safety and protection features that offer maximum flexibility and performance to the user. The device integrates an 8-bit microcontroller, a flexible power stage and an amplifier.

Application Fields

The L9942XP1 IC is a flexible and cost-effective solution for applications that require the control of brushless DC (BLDC) and brushed DC motors, such as in automotive and industrial sensors, home appliance motors, toys, lighting, and pumps.The IC is designed to provide high accuracy and performance while eliminating the complexity of the implementation by reducing the number of components required. It offers a wide range of features that allow the user to easily and quickly configure and program the device.

Working Principle

The L9942XP1 IC is a closed-loop motor control IC which works with a two-wire asynchronous brushless DC motor. The main components of this IC are an H-bridge, an in-line driver, a power stage, an amplifier and an 8-bit microcontroller, these devices are connected together in the following block diagram.

The IC works in a two-step process. First, it reads the rotary position of the motor and then it calculates the output signal to the motor. The IC also performs an internal tracking of the motor and then adjusts the output signal. It also monitors the status of the motor and if the motor is malfunctioning, it immediately shuts down the output signal.

The IC also communicates with the external environment using various interfaces such as SPI and I2C. This allows the user to program the IC with their own parameters and change them if necessary.

The L9942XP1 IC is ideal for applications that require high efficiency and performance. It also allows the user to easily integrate it into their system without any additional components.
