CS7054YDWR16

Overview

The CS7054YDWR16 is a monolithic integrated circuit designed primarily to control the rotor speed of permanent 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) signal. The device accepts a DC level input signal of 0 to 5V to control the output pulse width. It operates within a supply voltage range of 8V to 16V and supports an operating temperature range of -40°C to 125°C. The component is housed in a 16-SOIC package.

Feature Summary

• Provides low-side PWM FET control for driving power MOSFETs or IGBTs
• Accepts analog or filtered PWM input signals for precise duty cycle management
• Includes an on-chip linear regulator to support internal circuitry
• Supports recirculation of inductive current from motor loads

Applications

• Permanent magnet DC brush motor speed control
• Inductive load management such as solenoids
• Incandescent bulb dimming applications

Procurement Notes
