LV8827LFQA: Three-Phase PWM Brushless Motor Driver

The LV8827LFQA is a PWM-type driver IC designed for 3-phase brushless motors. The rotational speed can be controlled by inputting the PWM pulse from the outside, and changing Duty. The IC incorporates a latch-type constraint protection circuit.

Features
  • IO max = 1.5A (built-in output Tr)
  • Speed control and synchronous rectification using direct PWM input (supports 3.3V inputs)
  • 1-Hall FG output
  • Latch type constraint protection circuit (the latch is released by S/S and F/R.)
  • Forward/reverse switching circuit, Hall bias pin
  • Power save circuit (Power save in stop mode)
  • Current limiter circuit, Low-voltage protection circuit, Overheat protection circuit
  • Charge pump circuit, 5V regulator output.
  • Start/stop circuit (short brake when motor is to be stopped)
