General 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 V
without external speed-up capacitors
S
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 insures 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.

    ... Micrel Inc. Applications Information Supply Bypassing Charging and discharging large capacitive loads quickly requires large currents. For example, changing a 10,000pF load to 18V in 50ns requires 3.6A. The MIC4451/4452 has double bonding on the supply pins, the ground pins and output pins. This reduces parasitic lead inductance ...

    ... Micrel Inc. Input Stage The input voltage level of the MIC4451 changes the quiescent supply current. The N channel MOSFET input stage transistor drives a 320µA current source load. With a logic “1” input, the maximum quiescent supply current is 400µA. Logic “0” input level signals reduce quiescent current to 80µ ...

    ... Micrel Inc. Resistive Load Power Dissipation Dissipation caused by a resistive load can be calculated as where the current drawn by the load R = the output resistance of the driver when the output O is high, at the power supply voltage used.

    ... Micrel Inc. Transition Power Dissipation Transition power is dissipated in the driver each time its output changes state, because during the transition, for a very brief interval, both the N- and P-channel MOSFETs in the output simultaneously, and a current is conducted through them from V to ground. The transition power dissipation is ...
