MIC4416 Evaluation Board
IttyBittyLow-Side MOSFET Driver
Description
MIC4416 evaluation board assembled low-side switch 4.5V single-supply applications dual-supply applications. Requirements MIC4416 evaluation board requires power supplies, load, logic signal.

Operation
Connect evaluation board either configurations shown. function generator used control signal. Logic must 0.8V. Logic high must 2.4V exceeding Applying logic high control input will energize load; logic will de-energize load. MIC4416 demo board operates down 4.5V with logic-level MOSFET, such IRL3103. Because IRL3103 also ±20V maximum gate voltage rating, same MIC4416 evaluation board operates 18V. (Logiclevel MOSFET gates usually rated ±10V maximum. "MOSFET Selection" MIC4416 data sheet more information.) load supply separate operate anywhere within ratings MOSFET 30V). Supply Precautions MIC4416 evaluation board includes tantalum bypass capacitor supply input. Always apply power using power supply's on/off switch. Avoid applying power connecting supply input operating power supply. Applying power instantaneously tantalum capacitor cause capacitor failure.

"Operation: Supply Precautions" information safely using tantalum capacitors. Manufacturer's preliminary data sheet ratings: 10V, 34A, 25°C; 4.5V, 28A, 25°C. gate features logic-level performance with ±20V maximum rating. Heat sinking required higher currents. VDSS 30V.
Load Precautions 3.6k, 1/4W resistor used low-current demonstration load. When switching other loads, always stay within current rating MOSFET power supply. Note above. MOSFET located near edge evaluation board that fastened flat heat sink. Inductive loads require Schottky diode control inductive kick that occurs upon turnoff. Refer MIC4416 data sheet connection example. high current, leads resistive load also exhibit enough inductance cause significant inductive kick.
