Description
MIC4451 and MIC4452 CMOS MOSFET drivers are tough, 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 partci ect. 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 guarantee-freedom.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. characteristic • 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 equivalent input capacitance (typ.) 7pF • Low supply current 450µA with logic 1 input • Low output impedance 1.0Ω • Output voltage swing to within 25mV of ground or VS All the evaluation(0)
