... CMOS or bipolar drivers currently available. Their BiCMOS/ DMOS construction dissipates minimum power and provides rail-to-rail voltage swings. Primarily intended for driving power MOSFETs, the MIC4423/ 4424/4425 drivers are suitable for driving other loads (capacitive, resistive, or inductive) which require low- impedance, high peak currents, and fast switching times. ...

... MIC4423/4424/4425 Application Information Although the MIC4423/24/25 drivers have been specifically constructed to operate reliably under any practical circumstances, there are nonetheless details of usage which will provide better operation of the device. Supply Bypassing Charging and discharging large capacitive loads quickly requires large currents. For example, charging 2000pF from volts in 20ns requires a constant current of 1 ...

... TTL signals, or with CMOS powered from any supply voltage between 3V and 15V. The MIC4423/24/25 drivers can also be driven directly by the SG1524/25/26/27, TL494/95, TL594/95, NE5560/61/62/68, TSC170, MIC38C42, and similar switch mode power supply ICs. By relocating the main switch drive function into the driver rather than using the somewhat limited drive capabilities of a PWM IC ...
