Description
CS7054
The CS7054 is a monolithic integrat-
ed circuit designed primarily to
control the rotor speed of perma-
nent magnet, direct current (DC)
brush motors. It drives the gate of
an N channel power MOSFET or
IGBT with a user-adjustable, fixed
frequency, variable duty cycle,
pulse width modulated (PWM) sig-
nal. The CS7054 can also be used to
control other loads such as incan-
descent bulbs and solenoids.
Inductive current from the motor or
solenoid is recirculated through an
external diode.
The CS7054 accepts a DC level
input signal of 0 to 5V to control the
pulse width of the output signal.
This signal can be generated by a
potentiometer referenced to the on-
chip 5V linear regulator, or a fil-
tered 0% to 100% PWM signal also
referenced to the 5V regulator.
The IC is placed in a sleep state by
pulling the CTL lead below 0.5V. In
this mode everything on the chip is
shut down except for the on-chip
regulator and the overall current
draw is less than 275 μA. There are
a number of on-chip diagnostics
that look for potential failure modes
and can disable the external power
MOSFET.
