UCC235134-A/5-A,5.7-kVRMSOpto-CompatibleSingleChannelIsolatedGate Driver The UCC23513 is an Opto-compatible, singlechannel,isolated gate driver for IGBTs, MOSFETsand SiC MOSFETs, with 4.5-A source and 5.3-A sinkpeak output current and 5.7-KVRMS reinforcedisolation rating. The high supply voltage range of 33-V allows the use of bipolar supplies to effectivelydrive IGBTs and SiC power FETs. UCC23513 candrive both low side and high side power FETs. Keyfeatures and characteristics bring significantperformance and reliability upgrades over standardopto-coupler based gate drivers while maintainingpin-to-pin compatibility in both schematic and layoutdesign. Performance highlights include high commonmode transient immunity (CMTI), low propagationdelay, and small pulse width distortion. Tight processcontrol results in small part-to-part skew. The inputstage is an emulated diode (ediode) which meanslong term reliability and excellent agingcharacteristics compared to traditional LEDs. It isoffered in a stretched SO6 package with >8.5mmcreepage and clearance, and a mold compound frommaterial group I which has a comparative trackingindex (CTI) >600V. UCC23513 ’s high performanceand reliability makes it ideal for use in all types ofmotor drives, solar inverters, industrial powersupplies, and appliances. The higher operatingtemperature opens up opportunities for applicationsnot previously able to be supported by traditional
optocouplers.
UCC23513 is a single channel isolated gate driver, with an opto-compatible input stage, that can drive IGBTs,MOSFETs and SiC FETs. It has 4A peak output current capability with max output driver supply voltage of 33V.
The inputs and the outputs are galvanically isolated. UCC23513 is offered in an industry standard 6 pin (SO6)package with >8.5mm creepage and clearance. It has a working voltage of 1060-VRMS, reinforced isolation ratingof 5.7-KVRMS for 60s and a surge rating of 8-kVPK. It is pin-to-pin compatible with standard opto isolated gatedrivers. While standard opto isolated gate drivers use an LED as the input stage, UCC23513 uses an emulateddiode (or “e-diode”) as the input stage which does not use light emission to transmit signals across the isolationbarrier. The input stage is isolated from the driver stage by dual, series HV SiO2 capacitors in full differentialconfiguration that not only provides reinforced isolation but also offers best-in-class common mode transientimmunity of >150kV/us. The e-diode input stage along with capacitive isolation technology gives UCC23513several performance advantages over standard opto isolated gate drivers. They are as follows:
1. Since the e-diode does not use light emission for its operation, the reliability and aging characteristics ofUCC23513 are naturally superior to those of standard opto isolated gate drivers.
2. Higher ambient operating temperature range of 125℃, compared to only 105℃ for most opto isolated gatedrivers
3. The e-diode forward voltage drop has less part-to-part variation and smaller variation across temperature.
Hence, the operating point of the input stage is more stable and predictable across different parts andoperating temperature.
4. Higher common mode transient immunity than opto isolated gate drivers
5. Smaller propagation delay than opto isolated gate drivers
6. Due to superior process controls achievable in capacitive isolation compared to opto isolation, there is lesspart-to-part skew in the prop delay, making the system design simpler and more robust
7. Smaller pulse width distortion than opto isolated gate drivers

This reference design realizes a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. The UCC23513 gate driver used has a 6-pin wide body package with optical LED emulated inputs which enables its use as pin-to-pin replacement to existing opto-isolated gate drivers. This design shows that the UCC23513 input stage can be driven using all existing configurations used to drive opto-isolated gate drivers. In-phase shunt resistor based motor current sensing is done using AMC1300B isolated amplifier and DC link voltage, IGBT module temperature sensing using the AMC1311 isolated amplifier. The design uses a C2000™ LaunchPad™ for inverter control.
