Microchip Technology, Inc. 12A Inverting Peak Low Side MOSFET Driver MIC4451

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 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. Additional Features 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

The MIC4451 is an inverting 12A peak low-side MOSFET driver designed for high-current switching applications such as switch-mode power supplies and motor controls. It is available in an 8-pin plastic DIP or 8-pin SOIC package and operates over a supply voltage range of 4.5V to 18V. The device features matched rise and fall times of 25ns, a typical delay time of 30ns, and output impedance of 1.0Ω. It can drive capacitive loads up to 62,000pF and withstands negative input voltage swings down to -5V. The input is compatible with logic levels from 2.4V to V_S, and the output swings within 25mV of GND or V_S. Built with a BiCMOS/DMOS process, it is latch-up proof and has low quiescent current of 450µA with a logic high input. Duplicate pins for V_S, GND, and OUT must be externally connected.
