Working Principles

The MIC4426CM is a power MOSFET driver that efficiently controls the switching of power MOSFETs in various applications. It operates by receiving an input control signal (IN) and generating non-inverted output signals on the low-side (LO) and high-side (HO) outputs. These output signals drive the gate of the power MOSFET, allowing for fast switching between ON and OFF states.

The driver incorporates short-circuit protection, which safeguards against excessive current flow during fault conditions. Additionally, under-voltage lockout protection ensures that the driver remains inactive when the supply voltage falls below a certain threshold.
