Functional description
4.1
The power supply of both sides, VSL and VSH, is monitored by an under-voltage lockout block (UVLO) which enables opera-
tion 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.
Power supply
4.2
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).
Logic inputs
4.3
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.
Gate driver
4.4
This general purpose operational amplifier can be applied for current measurement of the driven low-side IGBT. It is dedi-
cated 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.
General purpose operational amplifier
4.5
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
In order to enable signal transmission across the isolation barrier between low-side and high-side driver, a coreless trans-
former 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 (dV
GNDH
/dt) or the magnetic flux (d
Φ
/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.
