DESCRIPTION
The MP6530 is a gate driver IC designed forthree-phase brushless DC motor driver applications. It is capable of driving three halfbridges consisting of 6 N-channel powerMOSFETs up to 60V.The MP6530 integrates a regulated chargepump to generate gate drive power, and uses abootstrap capacitor to generate a supplyvoltage for the high-side MOSFET driver. Aninternal trickle-charge circuit maintains sufficienthigh-side gate driver voltage even when anoutput is operated at 100% duty cycle.Internal protection features includeprogrammable short-circuit protection, over-
current protection, adjustable dead-time control,undervoltage lockout, and thermal shutdown.
The MP6530 is available in 28-pin, 9.7mm ×6.4mm TSSOP and 4mm x 4mm QFNpackages with an exposed thermal pad.
