General Description

The MIC4606 is an 85V full-bridge MOSFET driver that

features adaptive dead time and shoot-through protection.

The adaptive dead-time circuitry actively monitors

both sides of the full bridge to minimize the time

between high-side and low-side MOSFET transitions,

thus maximizing power efficiency. Anti-shoot-through

circuitry prevents erroneous inputs and noise from

turning both MOSFETs of each side of the bridge on at

the same time.

The MIC4606 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 MIC4606

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 MIC4606-1 features four independent inputs while

the MIC4606-2 utilizes two PWM inputs, one for each

side of the H-bridge. The MIC4606-1 and MIC4606-2

are available in a 16-pin 4 mm x 4 mm QFN package,

and a 16-pin 4 mm x 5 mm TSSOP package with an

operating temperature range of -40°C to +125°C.
