CONFIDENTIAL 2DMB51008CC Datasheet Gate Driver2DMB51008CC Overview Gate driver 2DMBxxxxxCC is a dual channel gate driver designed for IGBT and SiC MOSFET. The high breakdown voltage and low parasitic capacitance make it suitable for gate drives such as SiC MOSFET and IGBT. Features Ideal for drive of IGBT and SiC MOSFET Gate voltage : +15V/-10V ALL-IN-ONE (Built-in isolated DC / DC converter and gate drive circuit) Low parasitic capacitance (about 12pF) highly resistant to common-mode noise. Fast response : about 100nsec(typ) The gate drive circuit used a isolator. Input-to-Output dielectric withstand voltage : AC5000V Output CH1-to-Ouput CH2 dielectric withstand voltage : AC4000V Input-to-Output insulation distance : 14mm (clearancecreepage Output CH1-to-Output CH2 insulation distance : 7mm (clearance), 12mm(creepage DC/DC converter input voltage :1328V Signal input voltage : 3.3V,5V Overload protection (DC/DC converter) Overheat protection (DC/DC converter) Half bridge mode (Gate drive circuit) Desaturation protection (Gate drive circuit) Soft turn-off function (Gate drive circuit) Fault signal output function (Gate drive circuit) Miller clamp function (Gate drive circuit) Under-voltage lockout(UVLO) (Gate drive circuit) Safety satndards : UL508 (certification pending) Application Industrial inverter, power conditioner, etc Ciruit Image 2DMBxxxxxCC DST2 24 VO1+ 27 VGH2 28 VGL2 29 1 VIN+ 15V STO2 30 24V 2 VIN- MCL2 31 E/S2 26 3 VCC VO2- 25 3.3V 4 DTC1 5V 5 DTC2 6 ALM1 DST1 20 7 ALM2 VO1+ 17 8 MODE VGH1 16 9 RTC VGL1 15 10 INA STO1 14 11 INB MCL1 13 12 GND E/S1 18 VO1- 19 1 / 13 TAMURA CORPORATION TMRDM0028EN Rev.0.02 Jan, 2019CONFIDENTIAL 2DMB51008CC Datasheet Internal Block Diagram VIN+ VIN- VCC VO2+ DESAT detection DST2 ALM2 VGH2 VGL2 INB Isolator Soft-turn off STO2 1k Miller Clamp MCL2 E/S2 LOGIC VO2- Gate Drive Ch2 RTC Timer VO1+ DC/DC converter COM1 VIN+ VO1- DTC1 VIN- DTC2 Overheat VO2+ protection COM2 Overload Direct protection VO2- / Half- MOD Gate Drive Ch1 bridge 1k VO1+ DESAT detection DST1 ALM1 VGH1 VGL1 INA Isolator Soft-turn off STO1 Miller Clamp 1k MCL1 E/S1 GND VO1- Pin Connection Input Output Pin No. Pin No. Name Function Name CH Function Common 1 VIN+ Power supply for DC/DC converter(+) 13 MCL1 1 Miller clamp pin Common 2 VIN- Power supply for DC/DC converter(-) 14 STO1 1 Soft turn off pin 3 VCC - Power supply for drive circuit 15 VGL1 1 Gate OFF side pin 4 DTC1 1 Dead time adjustment 16 VGH1 1 Gate ON side pin 5 DTC2 2 Dead time adjustment 17 VO1+ 1 DC/DC converter output pin 6 ALM1 1 Alarm signal output 18 E/S1 1 Emittersource connection pin 7 ALM2 2 Alarm signal output 19 VO1- 1 DC/DC converter output pin 8 MOD - Mode select 20 DST1 1 Desaturation protection pin 9 RTC - Recovery time of protection circuit control 21 NONE - None 10 INA 1 Control input A 22 NONE - None 11 INB 2 Control input B 23 NONE - None 12 GND - Ground for drive circuit 24 DST2 2 Desaturation protection pin 25 VO2- 2 DC/DC converter output pin 26 E/S2 2 Emittersource connection pin 27 VO1+ 2 DC/DC converter output pin 28 VGH2 2 Gate ON side pin 29 VGL2 2 Gate OFF side pin 30 STO2 2 Soft turn off pin 31 MCL2 2 Miller clamp pin 2 / 13 TAMURA CORPORATION TMRDM0028EN Rev.0.02 Jan, 2019 LOGIC LOGIC
