... General Description MIC4120 and MIC4129 MOSFET drivers are resilient, efficient, and easy to use. The MIC4129 is an inverting driver, while the MIC4120 is a non-inverting driver. The MIC4120 and MIC4129 are improved versions of the MIC4420 and MIC4429. The drivers are capable of 6A (peak) output and can drive the largest MOSFETs with an improved safe operating margin ...

... For example, charging a 2500pF load to 18V in 25ns requires a 1.8 A current from the device power supply. The MIC4120/4129 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 ...

... V greater than the supply voltage. No damage will occur to MIC4120/4129 however, and it will not latch. The input appears as a 7pF capacitance, and does not change even if the input is driven from an AC source. Care should be taken so that the input does not go more than 5 volts below the negative rail ...

... MIC4120/4129 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 ...
