DESCRIPTION
The M56733AFP is a semiconductor integrated circuit designed as
a single chip controller for the FDD spindle motor. The IC is
equipped with a power amplifier, hole amplifier, FG amplifier,
oscillator, speed discriminator, and various types of protection
circuits.
Equipped with MOD pin that enables 3-speed switching with a
single pin, the M56733AFP is very convenient to make system
compact.
