Full-bridge 85V MOSFET drivers feature adaptive dead-time and shoot-through protection

27-02-2015 | Mouser Electronics | Power

Featuring adaptive dead time and shoot-through protection, Micrel's MIC4606
85V full-bridge MOSFET drivers are now stocked by Mouser.

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 applications such as full-bridge motor drivers, power inverters,
high-voltage step-down regulators, distributed power systems and stepper
motors.

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 4mmx4mm QFN package
with an operating temperature range of -40C to 125C.
