The LX1553IDM is a dual PWM DC-DC converter switch mode current-mode controller with independent internal drivers. It is discreetly integrated with a single-line output switch and a current-sense amplifier. This motor control system is designed for use with a range of DC brushless motors, for both synchronous and asynchronous designs. It can be used in a variety of applications, including washing machines, dishwashers, and air conditioners, as well as use in a range of different motors, from micro-motors to low power permanent magnet DC motors.

The LX1553IDM is a 3.0V to 5.5V motor control system, with an input current sense amplifier. It provides a fast response, high performance, and low-power current-mode PWM with separate internal drivers for both high-side and low-side devices. The LX1553IDM offers both auto-zero-load and off-time current-mode operation, along with a wide switching frequency range of up to 50kHz. It also features flexible system design with input voltage range of 6V to 15V and peak current sensing of 3A.

In addition to the features listed above, the LX1553IDM also offers an integrated low-side driver and open-loop protection, as well as cycle-by-cycle current limiting. It has a soft-start feature that allows for smooth power delivery without any output transients and in multiphase applications, the LX1553IDM can be run in parallel to increase efficiency and power.

The primary application for the LX1553IDM is for DC-DC switch mode motor control. It provides excellent motor speed control, improved power efficiency, higher power resolution and reduced RDS(on). It is also useful for controlling the speed of DC brushless motors and other types of controlled motors. This type of application requires a current mode PWM controller with integrated drivers and good transient response.

The working principle of the LX1553IDM involves regulating the supply voltage and then adjusting the direction of the current as it is applied to the motor. The current can be further regulated as to whether it is positive or negative. The actual process of controlling the rotation of the motor is done by using Pulse Width Modulation (PWM). PWM regulates the flow of current to the motor and adjusts the speed by changing the frequency and/or duty cycle of the signals.

The LX1553IDM is a very efficient and reliable motor control system. It is effective in controlling the speed of DC brushless motors, as well as any other type of controlled motor. Its integrated drivers, fast response and low-power current-mode PWM provide excellent control and power savings, while its wide switching frequency range of up to 50kHz makes it suitable for a wide range of applications. Additionally, its ability to be configured in parallel to support more demanding applications increases its flexibility and helps reduce overall operating cost.
