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’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 MC4606-1 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 and a
16-pin 4 mm x 5 mm TSSOP package with an
operating temperature range of –40°C to +125°C.
