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.
