LV8824QA PWM Driver IC

Ordering number : ENA2083 LV8824QA Bi-CMOS IC For Brushless Motor Drive PWM Driver IC http://onsemi.com Overview The LV8824QA is a PWM pre-driver IC suitable for use in 3-phase brushless motors. This IC was designed based on the assumption that Nch FETs are used as the upper and lower output transistors. The rotational speed is controllable by inputting P.

Features
