The LV8282PV-TLM-H is a motor driver that is part of the PMIC (Power Management Integrated Circuit) series. It is used in applications such as motor control and power supply management. The device is versatile and can interface with a variety of external devices such as MOSFETs, IGBTs and LDOs. The LV8282PV-TLM-H is available in both TQFN (Thin Quad Flat Non-Leaded Package) and VQFN (Voltage Quad Flat Non-Leaded Package) packages.

The LV8282PV-TLM-H is a highly efficient motor driver designed for synchronous brushless DC (BLDC) motors. It is capable of driving motors with high efficiency up to 4 Amps. The device uses a bipolar (Hall) control, with an internal Hall signal conditioning circuit, to generate a 3-phase sine-wave drive signal for the motor. The LV8282PV-TLM-H uses an internal PWM control algorithm to achieve high efficiency and low EMI (electromagnetic interference).

The LV8282PV-TLM-H features many features to ensure the highest performance. It has a built-in digital dead time control and current sensing system, which can detect the motor current and adjust the PWM output accordingly. The device also includes a low-voltage lockout circuit, which prevents motor damage when the supply voltage drops below a certain level. Additionally, the device has selectable regeneration and brake functions, which allow the user to adjust the properties of the motor, as well as a selectable over-current protection and filter functions.

The LV8282PV-TLM-H has a simple working principle. It uses an internal Clock Generator which generates a signal to the PWM and ADC (Analog-to-Digital Converter) to set the switching frequency and the current sensing is done through the winding and Hall signal. The LV8282PV-TLM-H then uses the PWM and control logic to generate the 3-phase sine-wave output to drive the motor.

The LV8282PV-TLM-H is a versatile and efficient motor driver, suitable for a wide range of applications. Its combination of features make it an ideal choice for applications such as BLDC motor control, power supply management, and automotive applications.
