ONSEMI LV8961HUWR2GEVK Evaluation Kit, LV8961HUWR2G, 3 Phase DC Brushless Motor Control, Power Management - Motor Control

LV8961HUWR2G evaluation kit is used to evaluate LV8961HUW IC. The LV8961H is a high performance, AEC-Q100 qualified, sensor-less three-phase BLDC motor controller with integrated gate drivers for driving external N-MOSFETs. An on-chip two-stage charge pump provides required gate voltage for a wide range of low RDS(ON) type external N-MOSFETs. The device offers a rich set of system protection and diagnostic functions such as over-current, over-voltage, short-circuit, under-voltage, over-temperature and many more. It supports open-loop as well as closed-loop speed control with user configurable start-up, speed setting and proportional/integral (PI) control coefficients, making it suitable for a wide range of motor and load combinations. With a built-in linear regulator for powering external circuits and a watchdog timer, the LV8961H offers a very small system solution.

• Embedded proprietary sensorless trapezoidal and sinusoidal commutation
• Selectable number of BEMF zero-cross detection window from 6, 3, 2, and 1 per electrical cycle
• Simple and effective lead angle adjustment setting by register
• Supports open-loop as well as closed-loop speed control
• Integrated gate drivers for driving six N-MOSFETs
• Two-stage charge pump for continuous 100% duty cycle operation
• 5V / 3.3V regulator and watchdog timer applications using an external microcontroller
• Configurable speed settings with linear characteristic
• PI control include acceleration/deceleration adjustment
• Direct access to PWM duty and FG cycle via SPI interface
