... General Description MIC4420, MIC4429 and MIC429 MOSFET drivers are tough, efficient, and easy to use. The MIC4429 and MIC429 are inverting drivers, while the MIC4420 is a non-inverting driver. They are capable of 6A (peak) output and can drive the largest MOSFETs with an improved safe operating mar- gin ...

... For example, charging a 2500pF load to 18V in 25ns requires a 1.8 A current from the device power supply. The MIC4420/4429 has double bonding on the supply pins, the ground pins and output pins This reduces parasitic lead inductance. Low inductance enables large currents to be switched rapidly ...

The MIC4420/4429 on the other hand, can source or sink several amperes and drive large capacitive loads at high frequency. The package power dissipation limit can easily be exceeded. Therefore, some attention should be given to power dissipation when driving low impedance loads and/or operating at high fre- quency ...

... MIC4420/4429 Capacitive Load Power Dissipation Dissipation caused by a capacitive load is simply the energy placed in, or removed from, the load capacitance by the driver. The energy stored in a capacitor is described by the equation 1 this energy is lost in the driver each time the load is charged or discharged, for power dissipation calculations the 1/2 is removed ...
