... General Description MIC4421A and MIC4422A MOSFET drivers are rugged, efficient, and easy to use. The MIC4421A is an inverting driver, while the MIC4422A is a non-inverting driver. Both versions are capable of 9A (peak) output and can drive the largest MOSFETs with an improved safe operating margin. The MIC4421A/4422A accepts any logic input from 2 ...

... Functional Diagram 0.1mA IN Functional Description Refer to the functional diagram. The MIC4422A is a non-inverting driver. A logic high on the IN produces gate drive output. The MIC4421A is an inverting driver. A logic low on the IN produces gate drive output. The output is used to turn on an external N- channel MOSFET. Supply V (supply) is rated for +4 ...

... Grounding The high current capability of the MIC4421A/4422A demands careful PC board layout for best performance. Since the MIC4421A is an inverting driver, any ground lead impedance will appear as negative feedback which can degrade switching speed. Feedback is especially noticeable with slow-rise time inputs. The MIC4421A 1µ ...

... Micrel, Inc. Input Stage The input voltage level of the MIC4421A changes the quiescent supply current. The N-Channel MOSFET input stage transistor drives a 320µA current source load. With a logic “1” input, the quiescent supply current is typically 500µA. Logic “0” input level signals reduce quiescent current to 80µ ...
