... 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. (See data sheet fraction of time the load is conducting (duty cycle) ...

... 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 ...
