Ordering number : ENA2058 LV8827LFQA Bi-CMOS IC For Brushless Motor Drive PWM Driver IC http://onsemi.com Overview 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.
