1 / 12 page © Semiconductor Components Industries, LLC, 2001 January, 2001 – Rev. 12 1 Publication Order Number: CS7054/D CS7054 Low Side PWM FET Controller The CS7054 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 CS7054 can also be used to control other loads such as incandescent 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 5.0 V to control the pulse width of the output signal. This signal can be generated by a potentiometer referenced to the on–chip 5.0 V linear regulator, or a filtered 0% to 100% PWM signal also referenced to the 5.0 V regulator. The IC is placed in a sleep state by pulling the CTL lead below 0.5 V. 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. Features • 200 mA Peak PWM Gate Drive Output • Patented Voltage Compensation Circuit • 100% Duty Cycle Capability • 5.0 V, ± 3.0% Linear Regulator • Low Current Sleep Mode • Overvoltage Protection • Overcurrent Protection of External MOSFET/IGBT • Output Inhibit http://onsemi.com A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week DIP–14 N SUFFIX CASE 646 1 14 VCC OUTPUT 1 PGND GND INH FLT IADJ COSC ISENSE+ ROSC ISENSE– CTL VREG NC 14 PIN CONNECTIONS AND MARKING DIAGRAMS SO–16L DW SUFFIX CASE 751G 1 16 VREG NC 1 16 ISENSE– NC ISENSE+ CTL IADJ ROSC INH COSC PGND FLT NC GND VCC OUTPUT Device Package Shipping ORDERING INFORMATION CS7054YN14 DIP–14 25 Units/Rail CS7054YDW16 SO–16L 46 Units/Rail CS7054YDWR16 SO–16L 1000 Tape & Reel SO–16L DIP–14 |
