Power management integrated circuits (PMICs) are a specialized type of integrated circuit that are used to facilitate the process of managing the power supply and subsequent power distribution within electronic devices. Many of the PMICs available today integrate multiple functions, such as voltage regulation, current regulation, switching, and power conditioning. One of the most commonly used PMICs is the LV8711T-TLM-H. This PMIC is used in motor applications, as it is designed to provide efficient, cost-effective solutions to motor control needs. In this article, we will take a look at the LV8711T-TLM-H and its applications and working principle in the field of motor drivers and controllers.

The LV8711T-TLM-H is a dual-channel power management IC (PMIC) designed specifically for motor applications. It is a single-output PMIC that features two integrated FETs that can handle up to 3A and peak loads up to 3.3A. This makes the LV8711T-TLM-H an ideal choice for applications in which both high power and low power are needed, such as in brushless DC (BLDC) motors and PMDC motors. In addition, the device also features integrated current sense, protection circuits, and an onboard 7-bit ADC.

The LV8711T-TLM-H is designed to work with a wide range of motor control algorithms, including open-loop, closed-loop, and vector-control. These features enable the device to easily and accurately control the behavior of BLDC and PMDC motors. In addition, the LV8711T-TLM-H provides a wide range of programmable parameters, such as the target speed and torque, thereby enabling users to adjust the behavior of the motor according to their needs. This makes the LV8711T-TLM-H well-suited for a wide range of motor control applications, such as robotics, home appliances, and industrial automation.

The LV8711T-TLM-H works on the principle of pulse width modulation (PWM) to control the speed of the motor. This is done by generating a high-frequency square-wave signal. The duty cycle of the signal is then adjusted to control the speed of the motor. The higher the duty cycle, the higher the speed and vice versa. The LV8711T-TLM-H also includes a proportional-integral-derivative (PID) controller, which can be used to adjust the speed of the motor accurately and quickly.

In addition, the LV8711T-TLM-H also includes a variety of protection features, such as current protection, thermal protection, and power supply protection. This ensures that the motor remains safe from damage due to overloads or other faults. The device also features an integrated soft-start function, which helps to reduce inrush current at startup, thereby reducing startup stress on the system.

Overall, the LV8711T-TLM-H is a highly reliable and efficient PMIC that is well-suited for motor driver and controller applications. Thanks to its integrated protection features and programmability, the device is able to accurately and quickly control the behavior of both BLDC and PMDC motors. This makes the LV8711T-TLM-H an ideal choice for a wide range of motor control applications.
