MIC4420YM

The MIC4420YM is a CMOS non-inverting MOSFET Driver capable of 6A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4420 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. This driver can replace three or more discrete components, reducing PCB area requirements, simplifying product design. Modern BiCMOS/DMOS construction guarantees freedom from latch-up. The rail-to-rail swing capability insures adequate gate voltage to the MOSFET during power up/down sequencing.

• Latch-up protected - Will withstand <gt/>500mA reverse output current
• Logic input will withstand negative swing up to 5V
• Output voltage swing to within 25mV of ground or VS
• 10000pF High capacitive load drive
• 2.5Ω Low output impedance
• 6pF Typical Low equivalent input capacitance
