Page 9 of 19 Secondary Figure 5 Output pinout diagram for 2ASC-12A1HP SiC Driver Core Channels 1 & 2 can be used interchangeably as the HI or LO side. On the HI Side the Temperature line should be floating and the DC Link monitor line should be grounded.

2ASC-12A1HP - 1200V Dual Channel High Performance SiC Core 1 Spec Sheet V6 © 2021 Microchip Technology Inc. Page 10 of 19 Drive Circuit Gate Voltage (Vgs) limiting Zener diodes are recommend limiting the exposure of the SiC MOSFET Gate to high voltage transients. The Zener diodes should be chosen based on the Vgs ratings of the SiC MOSFET. The 2ASC-12A1HP has separate Source & Sink outputs to separate the charging and discharging paths. The below equation can be used to estimate the drive current required for a given SiC MOSFET module: 𝐼𝑔𝑝𝑒𝑎𝑘 = 𝑉𝑔𝑠+ + 𝑉𝑔𝑠− 𝑅𝑔 + 𝑅𝐺 𝐼𝑔𝑝𝑒𝑎𝑘 – Peak Gate Current 𝑉𝑔𝑠+ – Positive Gate Voltage recommended by the SiC MOSFET Manufacturer 𝑉𝑔𝑠− – Negative Gate Voltage recommended by the SiC MOSFET Manufacturer 𝑅𝑔 – SiC MOSFET Module Internal Gate Resistance 𝑅𝐺 – External Gate Resistance on the Module Adapter Board Note: 𝐼𝑔𝑝𝑒𝑎𝑘 is a strong function of the module gate charge In the implementation shown below in Figure 6, a totem pole driver provides the 2ASC-12A1HP with ~20A peak current.

2ASC-12A1HP - 1200V Dual Channel High Performance SiC Core 1 Spec Sheet V6 © 2021 Microchip Technology Inc. Page 11 of 19 Short Circuit Protection - DSAT Circuit SiC devices are limited in their Short Circuit withstand capability of 2-3us. It is therefore important to adopt the appropriate short circuit protection parameters for the Gate Driver. DSAT Blanking time and DSAT threshold voltage are two such important parameters and are software configurable features on the 2ASC-12A1HP. DSAT protection with sense diodes is the recommended method, shown below in Figure 7. The DSAT lines are pulled up to +V_Sec via a 10kΩ pull up resistor on the 2ASC-12A1HP.

Page 15 of 19 Temperature and High Voltage PWM Monitoring The AgileSwitch 2ASC-12A1HP Driver provides two 31.5 kHz, 5.0V PWM output signals that monitor the thermistor temperature (isolated or non-isolated) and the DC Link Voltage (High Side drain to Low Side source) of the SiC MOSFET power module. The PWM signals have an output impedance of 510Ω. When combined with an external low pass filter, these signals represent a real time, isolated voltage for both High Voltage and Thermistor Temperature. A Sallen-Key active low pass filter can be used with these outputs as shown below with a 2 kHz cut-off frequency. The cut-off frequency can be optimized for your application. For simplicity, a simple RC low pass filter with 100 Hz cut-off frequency can also be used. Temperature Monitor The following table describes the correlation between the Thermistor Temperature and filtered Temperature Monitor Output. This is based on an NTC thermistor that measures 5kΩ @ 25°C. In the event that a thermistor is not part of the SiC Module the Recommended external Thermistor P/N is: TBD.

Page 16 of 19 DC Link Voltage Monitor The DC Link (HI Side drain to LO Side source) Monitor Output Voltage is 1% accurate from 50V to 1650V. The PWM output is the ratio of the DC Link Voltage / 1700V. For example, an 825V DC Link Voltage, the PWM output will be 50%. The linear equation for the Voltage Monitor PWM Output with a 2 kHz 4 pole filter is: 𝑉𝐷𝐶[𝑉] = 340 𝑋 𝑉𝑚𝑜𝑛𝑖𝑡𝑜𝑟 Generic Sample Factory Settings AgileSwitch drivers are designed to provide safe, secure and efficient operation of the SiC MOSFET power module, as well as to provide unparalleled information on the condition of the overall system. Generic samples are set at the factory to perform certain actions (e.g. turn off the HI side or LO side of the SiC MOSFET) and to report that a fault occurred based on performance parameters that occur outside of default ranges. The tables below show the generic configuration.

Page 17 of 19 Important Precautions Caution: Handling devices with high voltages involves risk to life. It is imperative to comply with all respective precautions and safety regulations. When installing the core and adapter board, please make sure that power is turned off. Hot swapping may cause damage to the IC components on the board. AgileSwitch assumes that the core and adapter board have been mounted on the SiC MOSFET prior to start-up testing. It is recommended that the user checks that the SiC MOSFET power modules are operating inside the Specified Operating Are a (SOA) as specified by the module manufacturer including short circuit testing under very low load conditions. Software Configurable Parameters The software configurable parameters on the 2ASC -12A1HP can be modified using a GUI developed by AgileSwitch. The code generated by this GUI is then downloaded to the driver. For further information regarding the parameters and instructions on programming the driver, please refer to the below documents.
