The LV8761V-MPB-E motor driver, controller and power management IC (PMIC) is a CMOS integrated circuit (IC) designed for automotive applications. The device is designed to operate on a voltage range from 4.0V to 45V and provides high-performance switching and power-management capabilities. It is available in 3 different configurations: single channel, dual channel and four-channel.

The single-channel configuration includes a half-bridge driver, a synchronous buck converter and LED drivers. The dual-channel configuration includes two half-bridge drivers, two synchronous buck converters and two LED drivers. The four-channel configuration includes four half-bridge drivers, four synchronous buck converters and four LED drivers.

The LV8761V-MPB-E PMIC can be used to control and configure a variety of motors. It is designed to provide robust power control and drive capability for motors such as brushless DC motors, permanent magnet synchronous, motors, nitride AC motors, delta AC motors, fractional-horsepower motors and brush-type motors. It has integrated protection features such as over-current, over-voltage, under-voltage and over-temperature protection. A programmable current limit feature prevents the motor from stalling. It is also equipped with a low-RDS (on) MOSFET for improved efficiency and lower switching loss.

The LV8761V-MPB-E PMIC has an integrated step-up/step-down quiescent current (ISC) converter, enabling the IC to convert an unregulated voltage up to 45V into a 3.3V or 5V regulated voltage. It also has an integrated power-on-reset (POR) circuit that ensures that the device is in a known state after power-up. Additionally, the device is equipped with an intelligent auto-resonant feature that eliminates the need for manual tuning of the switching frequency. This feature reduces the system design time and improves the overall efficiency of the motor.

The LV8761V-MPB-E PMIC has a working temperature range of -40 °C to 125 °C and is tested in accordance with AEC-Q100 standards. It is available in a Pb-free, 16-lead, 3mmx3mm QFN package with exposed pad and Pb-free lead-free terminals. The device is RoHS compliant and AEC-Q100 automotive qualified.

In summary, the LV8761V-MPB-E PMIC is an ideal solution for automotive applications that require high-performance switching and power management capabilities. It is designed to operate on a voltage range from 4.0V to 45V and has integrated protection features for improved reliability. The device’s low-RDS (on) MOSFET and intelligent auto-resonant feature reduce the system design time and improve the overall efficiency of the motor. The device is available in 3 different configurations, each suitable for a variety of motors and applications.
