Overview
The LB11820M is a direct PWM drive pre-driver IC that
is appropriate for 3-phase power brushless motors. This IC
can implement motor driver circuits that provide the
desired output capabilities (voltage and current) by the use
of appropriate discrete transistors in the output circuit. The
LB11820M is optimal for driving the large motors used in
air conditioners and on-demand hot water heaters.
