Product Overview

Evaluation board is designed to efficiently and effectively evaluate LV8814J, a 3-phase BLDC motor driver which is controlled by single hall sensor. A 180 degrees sinusoidal driving method is adopted and the IC can control motor with low vibration and the low noise. In addition, lead-angle adjustment is possible by an external pin. Lead angle value and lead angle slant can be adjusted independently. Thus, the device can be driven by high efficiency and low noise with various motors. The power element to drive a motor is built-in and contributes to high efficiency by low on resistance (0.5ohm). The hall sensor bias driver is equipped and a hall IC is supported as well. As a method of the rotary speed control of the motor, direct-PWM pulse input or DC voltage input can be chosen. The board enables users to develop their customized system solution by utilizing various features of LV8814J and provides real time development capabilities.
  • Supports 12.0V (typ) supply voltage
  • Speed control input, PWM duty cycle
  • Selectable hall sensor type, sensor or IC (factory default: configured for sensor type)
  • Configurable minimum PWM duty cycle (factory-default:14% for enable (start), 8% for disable (stop))
  • Configurable lead angle range and its proportional constant to rotational speed
  • Three phases motor output, hall sensor bias output, hall sensor input
  • PWM input, FG output
  • Monitoring outputs and setting inputs (optional)
  • Configuration setting resistors
