MCHPMIC4605-1YMT-TR
Overview
The MIC4605-1YMT-TR is an 85V Half-Bridge MOSFET driver designed for high-efficiency power conversion and motor control. It features advanced adaptive dead time and shoot-through protection to prevent cross-conduction in half-bridge configurations. Operating from a supply voltage of 5.5V to 16V, it can drive N-Channel MOSFETs with rapid 20ns rise and fall times.
Why Choose This Part
The IC includes an on-chip bootstrap diode which reduces external component count and saves PCB space in the 2.5mm x 2.5mm TDFN package. Its adaptive dead time circuitry automatically optimizes switching transitions to maximize efficiency while ensuring protection against simultaneous conduction of high and low-side FETs.
Applications
Key Specifications
Getting Started
When designing with this part, ensure the VDD bypass capacitor is placed close to the pins and choose a bootstrap capacitor based on the gate charge of the high-side MOSFET. For prototyping, Microchip offers the ADM00661 evaluation board which demonstrates the MIC4605 in a typical application circuit.
