NCD5702 - High Current IGBT Gate Driver

1 Semiconductor Components Industries, LLC, 2017 April, 2018 Rev. 11 Publication Order Number: NCD5702 /DNCD5702 high Current igbt GateDriverThe NCD5702 is a high Current , high performance stand aloneIGBT Driver for high power applications that include solar inverters,motor control and uninterruptible power supplies. The device offers acost effective solution by eliminating many external protection features include Active Miller Clamp, accurateUVLO, EN input, DESAT protection and Active open drain FAULT output. The Driver also features an accurate V output and separatehigh and low (VOH and VOL) Driver outputs for system designconvenience.

2 The Driver is designed to accommodate a wide voltagerange of bias supplies including unipolar and bipolar voltages. It isavailable in a 16 pin SOIC high Current Output (+4/ 6 A) at igbt Miller Plateau Voltages Low Output Impedance of VOH & VOL for Enhanced igbt Driving Short Propagation Delays with Accurate Matching Direct Interface to Digital Isolator/Opto coupler/Pulse Transformerfor Isolated Drive, Logic Compatibility for Non isolated Drive Active Miller Clamp to Prevent Spurious gate Turn on DESAT Protection with Programmable Delay Enable Input for Independent Driver Control Tight UVLO Thresholds for Bias Flexibility Wide Bias Voltage Range including Negative VEE Capability This Device is Pb Free.

4 PIN FUNCTION DESCRIPTIONPin input allows additional gating of VOH and VOL, and can be used when the Driver outputneeds to be turned off independent of the Microcontroller input. EN is internally clamped to 5 V andhas a pull up resistor of 1 signal to control the output. In applications which require galvanic isolation, VIN is generatedat the opto output, the pulse transformer secondary or the digital isolator output. VOIH/VOL signal isin phase with VIN. VIN is internally clamped to 5 V and has a pull down resistor of 1 MW to ensurethat output is low in the absence of an input signal.

5 A minimum pulse width is required at VIN be-fore VOH/VOL are V Reference generated within the Driver is brought out to this pin for external bypassing and forpowering low bias circuits (such as digital isolators).FLT4 OFault open drain output (active low) that allows communication to the main controller that the driverhas encountered a fault condition and has deactivated the output. Open drain allows easy setting of(inactive) high level and parallel connection of multiple fault to 10k pull up resistor recommended. Truth Table is provided in the datasheet to indicateconditions under which this signal is asserted.

6 Capable of driving optos or digital isolators whenisolation is pin provides a convenient connection point for bypass capacitors ( REF) on the left side ofthe ,8xPins not internally No connection is for detecting the desaturation of igbt due to a fault condition. A capacitor connected to thispin allows a programmable blanking delay every ON cycle before DESAT fault is processed, thuspreventing false bias supply for the Driver . The operating range for this pin is from UVLO to the maximum. Agood quality bypassing capacitor is required from this pin to GND and should be placed close to thepins for best high output that provides the appropriate drive voltage and source Current to the igbt low output that provides the appropriate drive voltage and sink Current to the igbt gate .

7 VOLis actively pulled low during start up and under Fault pin should connect to the igbt Emitter with a short trace. All power pin bypass capacitorsshould be referenced to this pin and kept at a short distance from the negative voltage with respect to GND can be applied to this pin and that will allow VOL to go to anegative voltage during OFF state. A good quality bypassing capacitor is needed from VEE to a negative voltage is not applied or available, this pin must be connected to version of the VEE pin for any signal trace connection. VEE and VEEA are internally clamping for the igbt gate during the off period to protect it from parasitic turn on.
