LV8827LFQA

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.) 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.
