Applications • • • • • • • • Switch Mode Power Supplies Motor Controls Pulse Transformer Driver Class-D Switching Amplifier Line Drivers Driving MOSFET or IGBT Parallel Chip Modules Local Power ON/OFF Switch Pulse Generators Both versions are capable of 12A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4451/52 accept 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. MIC4451/52 drivers can replace three or more discrete components, reducing PCB area requirements, simplifying product design, and reducing assembly cost. Modern Bipolar/CMOS/DMOS construction ensures freedom from latch-up. The rail-to-rail swing capability of CMOS/DMOS ensures adequate gate voltage to the MOSFET during power up/down sequencing. Because 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.

For example, changing a 10,000 pF load to 18V in 50 ns requires 3.6A. The MIC4451 and MIC4452 have double bonding on the supply pins, the ground pins, and output pins. This reduces parasitic lead inductance. Low inductance enables large currents to be switched rapidly. It also reduces internal ringing that can cause voltage breakdown when the driver is operated at or near the maximum rated voltage. Internal ringing can also cause output oscillation due to feedback. This feedback is added to the input signal because it is referenced to the same ground. To ensure low supply impedance over a wide frequency range, a parallel capacitor combination is recommended for supply bypassing. Low inductance ceramic disc capacitors with short lead lengths (
