General Description

The MIC4605 is an 85V half-bridge MOSFET driver

that features adaptive dead time and shoot-through

protection. The adaptive dead-time circuitry actively

monitors the half-bridge outputs to minimize the time

between high-side and low-side MOSFET transitions,

thus maximizing power efficiency. Shoot-through

protection circuitry prevents erroneous inputs and noise

from turning both MOSFETS on at the same time.

The MIC4605 also offers a wide 5.5V to 16V operating

supply range to maximize system efficiency. The low

5.5V operating voltage allows longer run times in

battery-powered applications. Additionally, the MIC4605

device’s adjustable gate drive sets the gate drive voltage

to VDD for optimal MOSFET RDS(ON), which minimizes

power loss due to the MOSFET’s RDS(ON).

The MIC4605 is available in an 8-pin SOIC package

and a tiny 10-pin 2.5 mm x 2.5 mm TDFN package.

Both packages have an operating junction temperature

range of -40°C to +125°C.
