描述 Description
MIC4421A and MIC4422A MOSFET gate drivers are rugged, efficient, and easy to use. The MIC4421A is an inverting driver, while the MIC4422A is a non-inverting driver. Both versions are capable of 9 A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4421A/4422A 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 5 V without damaging the part. Additional circuits protect against damage from electrostatic discharge. MIC4421A/4422A gate 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 helps ensure 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.
特性 Features
• 9 A peak (typical)
• Wide operating range: 4.5 V to 18 V (typical)
• Minimum pulse width: 50 ns
• Latch-up proof: fully isolated process is inherently immune to any latch-up.
• Input will withstand negative swing of up to 5 V
• High capacitive load drive: 47,000 pF
• Low delay time: 15 ns (typical)
• Logic high input for any voltage from 2.4 V to VS
• Low equivalent input capacitance (typical): 7 pF
• Low supply current: 500 µA (typical)
• Output voltage swing to within 25 mV of ground or VS
