CS7054YN14

Overview

The CS7054YN14 is a monolithic integrated circuit designed primarily to control the rotor speed of permanent magnet, direct current (DC) brush motors. It functions as a low-side PWM FET controller that drives the gate of an N-channel power MOSFET or IGBT with a user-adjustable, fixed frequency, variable duty cycle, pulse width modulated signal. The device accepts a DC level input signal of 0 to 5V to control the output pulse width. Inductive current from the motor or solenoid is recirculated through an external diode.

Feature Summary

• Generates a user-adjustable, fixed frequency, variable duty cycle PWM signal for driving N-channel power MOSFETs or IGBTs.
• Accepts a 0 to 5V DC level input signal to control the pulse width of the output signal.
• Designed to control rotor speed of permanent magnet DC brush motors and other loads such as incandescent bulbs and solenoids.

Applications

• Permanent magnet DC brush motor speed control
• Incandescent bulb control
• Solenoid control

Procurement Notes

Verify the manufacturer designation carefully, as the CS7054 series is documented under Cherry Semi rather than onsemi. Confirm the specific suffix 'YN14' corresponds to the PDIP-14 package variant in official Cherry documentation. Ensure compatibility with automotive temperature grades if required by the application design specifications.

Selection Notes

Select this component when a dedicated low-side PWM controller for DC brush motors is required. It is suitable for applications needing a simple interface with a 0-5V control signal. Consider the PDIP-14 package constraints and verify that the external MOSFET or IGBT drive requirements align with the controller's output capabilities.

Part Context

The CS7054 is part of a family of low-side PWM FET controllers. The CS7054YN14 specifically refers to the version housed in a 14-pin plastic DIP package. This family is distinct from onsemi's broader portfolio of gate drivers and motor drivers, representing a specialized solution for basic DC motor speed regulation tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other low-side PWM controllers if sourcing from alternative manufacturers.
