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.
