IttyBitty Low-Side MOSFET Driver
Description
The MIC4416 evaluation board is an assembled low-side switch for 4.5V to 18V single-supply applications and 0V to 30V dual-supply applications. Requirements The MIC4416 evaluation board requires one or two power supplies, a load, and logic signal.

Load Precautions A 3.6k, 1 / 4W resistor can be used as a low-current demonstration load. When switching other loads, always stay within the current rating of the MOSFET and power supply. See Note 2, above. The MOSFET is located near the edge of the evaluation board so that it can be fastened to a flat heat sink. Inductive loads require a Schottky diode to control the inductive kick that occurs upon turnoff. Refer to the MIC4416 data sheet for a connection example. At high current, leads to a resistive load may also exhibit enough inductance to cause significant inductive kick.
