TOOLS BENEFITS FEATURES » High Efficiency • Adapative dead-time circuitry automatically adjusts
the dead time between high-and low-side MOSFET for
minimal losses » Robust Architecture • 85V operation protects against voltage spikes caused by
a motor’s back electromagnetic force (EMF)
• Anti-shoot-through protects against cross conduction
• Overcurrent protection » Extended Run Time • Wide gate drive range: 5.5V to 16V
• Low 4.9V undervoltage lockout (UVLO) allows longer
run time for battery-operated motors MEDICAL EQUIPMENT » Small Footprint • 28-pin 4mm × 5mm QFN and 28-pin TSSOP package
options available
• Integrated bootstrap diodes REMOTE CONTROLLED

DESCRIPTION
The MIC4607 is an 85V, three-phase MOSFET driver. The MIC4607 features adaptive
dead-time circuitry which actively monitors key voltages in each of the three phases
to minimize the dead-time between the high-and low-side transitions and antishootthrough circuitry, preventing erroneous inputs and noise from simultaneously
turning on any of the three phase’s high-and low-side MOSFETs.
The MIC4607 additionally features fast (35ns) propagation delay time and 20ns driver
rise/fall times for a 1nF capacitive load. TTL inputs can be separate high-and low-side …
