62EM1-Programmable 62mm Electrical Series
Optimized for Silicon Carbide (SiC) MOSFET Modules
Overview
The AgileSwitch 62EM1-62mm Electrical driver provides monitoring and fault reporting information to enable
better control and analysis of SiC MOSFET-based power systems. The 62EM1 provides up to 20 Amps of peak
current at an operating frequency up to 200 kHz. The driver includes isolated HI and LO Side DC/DC converters
and provides 7 fault conditions that are reported as a combination of the 3 fault lines via the 20 pin control header.
All AgileSwitch drivers use automotive temperature grade components and allow for modifying settings of gate
resistors.

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.

DC Link Voltage Monitor – 1200V
The DC Link (HI Side drain to LO Side source) Monitor Output Voltage is 1% accurate from 25V to 975V. The
PWM output is the ratio of the DC Link Voltage / 1000V. For example, a 500V 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:

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.

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 electronics 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.
