Product Introduction

MIC4451 and MIC4452 CMOS MOSFET drivers are robust, efficient, and easy to use. The MIC4451 is an inverting driver, while the MIC4452 is a non-inverting driver.

Both versions are capable of 12A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4451/4452 accepts any logic input from 2.4V to Vs without external speed-up capacitors or resistor networks. Proprietary circuits allow the input to swing negative by as much as 5V without damaging the part. Additional circuits protect against damage from electrostatic discharge.

MIC4451/4452 drivers can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost.

Modern Bipolar/CMOS/DMOS construction guarantees freedom from latch-up. The rail-to-rail swing capability of CMOS/DMOS insures adequate gate voltage to the MOSFET during power up/down sequencing. Since these devices are fabricated on a self-aligned process, they have very low crossover current, run cool, use little power, and are easy to drive.

Features

  • BiCMOS/DMOS construction
  • Latch-up proof: fully-isolated process is inherently immune to any latch-up
  • Input will withstand negative swing of up to 5V
  • Matched rise and fall times: 25ns
  • High peak output current: 12A peak
  • Wide operating range: 4.5V to 18V
  • High capacitive load drive: 62,000pF
  • Low delay time: 30ns (typ.)
  • Logic high input for any voltage from 2.4V to Vs
  • Low supply current 450μA with logic 1 input
  • Low output impedance: 1.0Ω
  • Output voltage swing to within 25mV of GND or Vs
  • Low equivalent input capacitance (typ.): 7pF

Applications

  • - Switch mode power supplies - Motor controls - Pulse transformer driver - Class-D switching amplifiers - Line drivers - Driving MOSFET or IGBT parallel chip modules - Local power ON/OFF switch - Pulse generators
