EiceDRIVERTM 2ED020I12-F
1 Overview
The 2ED020I12-F is a high voltage, high speed power IGBT and MOSFET driver of the eupec EiceDRIVERTM family with interlocking high and low side referenced output channels. The floating high side driver may be supplied directly or by means of a bootstrap diode and capacitor. In addition to the logic input of each driver the 2ED020I12-F is equipped with a dedicated shutdown input. All logic inputs are compatible with 3.3 V and 5 V TTL. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use in high frequency applications. Both drivers are designed to drive an n-channel power IGBT or MOSFET which operates up to 1200 V. In addition, a general purpose operational amplifier and a general purpose comparator are provided, which may be used e.g. for current measurement or over current detection. Product Highlights * Fully operational to 1200 V * Gate drive supply range from 13 to 18 V * Gate drive currents of +1 A / -2 A * Matched propagation delay for both channels * High dV/dt immunity * General purpose operational amplifier * General purpose comparator Features * Floating high side driver * Under-voltage lockout for both channels * 3.3 V and 5 V TTL compatible inputs * CMOS Schmitt-triggered inputs with internal pull-down * CMOS Schmitt-triggered shutdown with internal pull-up * Non-inverting inputs * Interlocking inputs * Dedicated shutdown input with internal pull-up * IEC compliant (pending) * UL recognized (pending)
1.1
Coreless transformer (CLT) technology
In various IGBT and power MOSFET driver stages are optocoupler, level shifter or discrete transformer included to overcome the isolation barrier between the low side input and high side output. All of them have their typical advantages and disadvantages. As an alternative for low and medium power applications the coreless transformer technology combines almost all advantages and at the same time avoiding almost all disadvantages of these devices by a very cost efficient way and high voltage isolation capability. The principle function of the CLT is realized by two coils which are compounded on silicon within one integrated circuit. The isolation between these coils can withstand in the current design at least up to 1200 V whereby a functional isolation is achieved. Figure 1 shows a schematic of the internal stages of the IC.

4.1
Functional description
Power supply
The power supply of both sides, VSL and VSH, is monitored by an under-voltage lockout block (UVLO) which enables operation of the corresponding side when the supply voltage reaches the "on" threshold of 12 V. Afterwards the internal voltage reference and the biasing circuit are enabled. When the supply voltage (VSL, VSH) drops below the "off" threshold of 11 V the circuit is disabled.
4.2
Logic inputs
The logic inputs InH, InL and /SD are fed into Schmitt-Triggers with thresholds compatible to 3.3 V and 5 V TTL. When /SD is enabled (low), InH and InL are disabled. If InH is high (while InL is low), OutH is enabled and vice versa. However, if both signals are high, they are internally disabled until both signals get low again. This is due to the interlocking logic of the device (see also Figure 5).
4.3
Gate driver
2ED020I12-F features two hard-switching gate drivers with n-channel output stages capable to source 1 A and to sink 2 A peak current. Both drivers are equipped with active-low-clamping capability. Furthermore, they feature a large ground bounce ruggedness in order to compensate ground bounces caused by a turn-off of the driven IGBT.
4.4
General purpose operational amplifier
This general purpose operational amplifier can be applied for current measurement of the driven low-side IGBT. It is dedicated for fast operation with a gain of at least 10. The OP is equipped with a -0.1 V to 2 V input stage and a rail-to-rail output stage which is capable to drive 5 mA and is dedicated to drive an A/D converter.
4.5
General purpose comparator
The general purpose comparator can be applied for over-current detection of the low side IGBT. A dedicated offset as well as a pull-up and pull-down resistor has been introduced to its inputs for security reasons.
4.6
CLT
In order to enable signal transmission across the isolation barrier between low-side and high-side driver, a coreless transformer is employed. Signals, that are to be transmitted, are specially encoded by the transmitter and correspondingly restored by the receiver. In this way EMI due to variations of GNDH (dVGNDH/dt) or the magnetic flux (d/dt) can be suppressed. To compensate the additional propagation delay of transmitter, coreless transformer and receiver, a dedicated propagation delay is introduced into the low-side driver.

Application Notes
Power Supply
The floating high side driver may be supplied directly or by means of a bootstrap diode and capacitor. Either way, for a correct power-up it is recommended to put at the pins VSH and VSL an electrolytic or tantalum capacitor and additionally a ceramic capacitor of approximately 100 nF. The size of the electrolytic or tantalum capacitor depends on the gate capacitances of the driven IGBT or MOSFET, the switching frequency and additional gate resistors and/or capacitors. For a safe start-up with a bootstrap diode and capacitor it is recommended first to switch on the low-side IGBT. Thus, the capacitor can be charged through the diode and provides sufficient gate voltage.
Figure 10
Bootstrap circuit
7.2
Ground reference
The pins GND and GNDL have to be connected externally through the shortest possible way. Thus, different ground references result for different applications as shown for instance in Figure 11.

7.3 Operational Amplifier
To minimize the current consumption when the operational amplifier is not used, it is necessary to connect both inputs properly. For instance connect pin OP+ to 5 V and pin OP- to 0 V or vice versa.

OPA not used
The operational amplifier is designed to operate with a minimum gain of 10, so that its output OPO has a stable behavior.

7.4 Comparator
The comparator has a designed input offset voltage of typical -30 mV to prioritize the CP+ input against the CP- input. If both input signals have the same potential, the output /CPO goes to low impedance. In the following some example circuits using the general purpose comparator:
