The MIC4452 is a non-inverting 12A peak low-side MOSFET driver available in 8-pin SOIC, 8-pin DIP, and 5-pin TO-220 packages. It operates from 4.5V to 18V, with a peak output current of 12A and rise/fall times up to 60ns. Input logic levels from 2.4V to VSS are supported, including negative swings up to 5V without damage. Output swing reaches within 25mV of supply or ground. The device features latch-up-proof BiCMOS/DMOS construction, ESD protection, and input capacitance of 7pF. Operating temperature ranges from -40°C to +85°C for SOIC and DIP; the TO-220 variant is rated 0°C to +70°C. Maximum junction temperature is 150°C. Thermal impedance for TO-220 is 10°C/W, with 12.5W maximum power dissipation.
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 part. Additional circuits protect 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 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.
