62EM1 – Programmable 62mm Electrical Series PRELIMINARY 62EM1 - 62mm Electrical Master 1 Spec Sheet V09 Page 4 of 17 Temperature and High Voltage PWM Monitoring: The AgileSwitch 62EM1 Driver provides two 31.5 kHz, 5.0V PWM output signals that monitor the thermistor temperature (non-isolated) and the DC Link Voltage(isolated) (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. Figure 2: Example of external 2 kHz low pass filter

62EM1 – Programmable 62mm Electrical Series PRELIMINARY 62EM1 - 62mm Electrical Master 1 Spec Sheet V09 Page 12 of 17 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.

62EM1 – Programmable 62mm Electrical Series PRELIMINARY 62EM1 - 62mm Electrical Master 1 Spec Sheet V09 Page 13 of 17 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 ribbon cable, please make sure that power is turned off. Multi-signal values are sent along this ribbon cable, thus hot swapping may cause damage to the IC components on the board. AgileSwitch assumes that the gate drive board has 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 Area (SOA) as specified by the module manufacturer including short circuit testing under very low load conditions. Recommended Start-Up Testing 1. Connect the driver through the 20 pin control header to your drive ele ctronics and supply the driver with +15V. 2. Send the fault reset pin, pin 19, a low signal. Return pin 19 to a high condition. (If the driver is configured for Auto Reset, you may ignore this step.) 3. Check the gate voltage: a) For the off-state, the nominal gate voltage should be -6V to -4V. (Note 3) b) For the on state, it is +17 to +21V. (Note 3) c) Check that the supply current of the driver is within spec with inactive trigger signals and then at the desired switching frequency. 4. The system is now ready for application testing under load conditions. 5. Check thermal conditions to verify that the system is operating within specified temperature range. 6. Do NOT apply High Voltage to the SiC Module without first applying power to the GDB.
