3 / 6 page APPLICATION NOTES IN MSK 4900 PIN DESCRIPTIONS VCC - is the bias supply voltage for supplying the input logic and the power supply for the isolated output. This pin should be bypassed to GND with a 4.7µF tantalum capacitor and a 0.1µF ceramic capacitor as close this pin and GND as pos- sible. GND - is the Vcc supply return for the input logic and the internal isolated supply. This GND is completely isolated from the output section. No output returns should connect to this GND in order to preserve isolation. All Vcc bias supply by- pass connections should be made as close to this pin as pos- sible. An input ground plane is the most preferred layout for assuring good, low impedance ground, shielding of inputs from noise, etc. HI - is the input logic pin for commanding the high-side gate drive to turn on. This logic input is TTL compatible. This in- put is exclusive OR'd with LO to protect against simultaneous turn on of both the high-side and low-side gate drive. LO - is the input logic pin for commanding the low-side gate drive to turn on. This logic input is TTL compatible. This in- put is exclusive OR'd with HI to protect against simultaneous turn on of both the high-side and low-side gate drive. X FAULT - is an open collector output for indicating either a de-saturation condition or an undervoltage condition for the gate drive. This output will be cleared upon activation of X FAULT CLEAR. X FAULT CLEAR - is a logic input pin for clearing a FAULT condition. This input should not be activated until shutdown of the affected gate is complete. Allow (TBD) µSec after FAULT before activation of this pin. X ON - is the gate drive output pin for turning the gate on. This pin will source TBD current. A separate gate resistor shall be selected to tailor the turn-on characteristics. This pin will turn on to +15V. NOTE: X = HI or LO X OFF - is the gate drive output pin for turning the gate off. This pin will sink TBD current. A separate gate resistor shall be selected to tailor the turn-off characteristics. This pin will turn off to -5V. DE-SAT SENSE X - is the input connection for sensing de- saturation. This pin shall be connected to the collector of the IGBT. This pin is blanked during switching so that it will not false trip. X VDD - is the pin for the floating gate supply voltage. TBD capacitance shall be connected between this pin and X VSS as close to the pin as possible. Nominally, this voltage will be +15V with respect to the RETURN X pin and the emitter of the IGBT. X VSS - is the return pin for the floating gate supply voltage. TBD capacitance shall be connected between this pin and X VDD as close to the pins as possible. Nominally, this voltage will be -5V with respect to the RETURN X pin and the emitter. SS X - is the soft shutdown pin for slowly turning the gate off after a de-saturation condition. This pin is a separate gate turn-off path and requires a separate gate resistor for this spe- cial turn-off approach. The resistor should be sized to keep di/ dt from being too high after the de-sat condition. RETURN X - is the pin for the emitter reference. This pin will be at zero volts to +15V to -5V for the gate drive voltage. 3 PRELIMINARY Rev. - 1/07 |
