MIC4421 - 9A-Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process

General Description

MIC4421 and MIC4422 MOSFET drivers are rugged, efficient, and easy to use.

The MIC4421 is an inverting driver, while the MIC4422 is a non-inverting driver.

Both versions are capable of 9A (peak) output and can drive the largest MOSFETs with an improved safe operating margin.

Key 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 9A Peak.
  • Wide Operating Range 4.5V to 18V.
  • High Capacitive Load Drive 47,000pF.
  • Low Delay Time 30ns Typ.
  • Logic High Input for Any Voltage from 2.4V to VS.
  • Low Equivalent Input Capacitance (typ).

ral Description MIC4421 and MIC4422 MOSFET drivers are rugged, efficient, and easy to use. The MIC4421 is an inverting driver, while the MIC4422 is a non-inverting driver. Both versions are capable of 9A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4421/4422 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.
