1 Rev 0.1 ID7T0610AD 3-phase Gate Driver integrated with LDO hh General Description The ID7T0610AD is a gate driver IC designed for three phase brushless DC motor driver applications. It is capable of driving three half bridges consisting of 6 N-channel power MOSFETs. The ID7T0610AD integrates a LDO to generate local power for microcontrollers or other circuitry. Internal protection features include dead-time for over-shoot prevention, and under voltage lockout. The ID7T0610AD is available in wafer level. Features VCC voltage range from 8V to 13.5V 5V Low-drop regulator supply UVLO protection Built in 180ns dead-time to prevent cross-conduction Built in bootstrap diode for gate driver circuit 1A/1A sink/source three-phase gate drivers High side breakdown voltage is larger than 80V Applications 3-phase, brushless DC motors and permanent magnet synchronous motors Power drills E-bikes Typical Application MCUN-ChannelMOSFETsMEN_GATEPWMSPIID7T0610AD3 - PhaseBrushlessPre-DriverLDOProtectionPowerGate DriveSenseUP to 60V Package 2 Rev 0.1 ID7T0610AD 3 Gate Driver integrated with LDO ICOrder Information Part Number Order Code Package Type ID7T0610AD ID7T0610ADSTC-R1 QSOP24 - PAD Information VSSVCCHIN1LIN1HIN2HIN3SDID7T0610AD24VB1HO1VS1VB2HO2VS2VB3HO3VS3NC2322212019181716151413121110987654321VREG5LIN2LO3LO2LO1LIN3NC 3 Rev 0.1 ID7T0610AD 3 Gate Driver integrated with LDO ICPAD Definitions PIN NAME PIN FUNCTION VCC The supply voltage of LDO and gate driver VREG5 5V Liner regulator output VSS Ground SD Shutdown logic HVIC HIN1,2,3 Logic inputs for high-side gate driver outputs LIN1,2,3 Logic inputs for low-side gate driver outputs LO1,2,3 Low-side driver outputs VB1,2,3 High-side gate drive floating supply HO1,2,3 High-side driver outputs VS1,2,3 High voltage floating supply return 4 Rev 0.1 ID7T0610AD 3 Gate Driver integrated with LDO ICFunctional Block Diagram VREG5HIN1,2,3LIN1,2,3DeadTime & Control LogicVB1,2,3HO1,2,3VS1,2,3Level ShifterLevel ShifterVCCSDLO1,2,3VSSUVLO & POR5V LDOBGR 5 Rev 0.1 ID7T0610AD 3 Gate Driver integrated with LDO ICAbsolute Maximum Ratings Exceeding these ratings may damage the device.
