1EDS - slew rate control IGBT driver IC
INN inverting driver input
INN control signal for the driver output while INP is set to high. The IGBT is turned on, if INN is set to low, and is
turned off, if INN is set to high, respectively. A minimum pulse width is required to prevent from glitches while
controlling the IGBT. An internal pull-up resistor ensures that the IGBT is kept in off-state, if terminal INN is left
unconnected.
The reference terminal for INN is PADN.
INP non-inverting driver input
INP control signal for the driver output while INN is set to low. The IGBT is turned on, if INP is set to high, and is
turned off, if INP is set to low, respectively. A minimum pulse width is required to suppress glitches while
controlling the IGBT. An internal pull-down resistor ensures that the IGBT is kept in off-state, if terminal INP is
left unconnected.
The reference terminal for INP is PADN.
EN input
Terminal EN needs to be set high for INP and INN to control the IGBT switching.
The EN input terminal serves two purposes:
Feature 1: Enable / shutdown of the output side. The IGBT is turned off by a soft turn-off, if terminal EN is set to
low. A minimum pulse width is defined to help suppress glitches on terminal EN.
The IGBT is switched on without preboost on the rising edge of terminal EN, if terminal INP is set high and
terminal INN is set low before activating EN.
Feature 2: Resets the desaturation or overcurrent condition signaled on terminal /FLT, if terminal EN is set to
low for more than 800 ns. A reset is asserted at the rising edge of terminal EN.
The reference terminal for EN is PADN.
SPEED
IGBT on-state gate current setting sent from input side. This is an analog input terminal. The reference voltage
of the internal ADC is PADP.The reference terminal for SPEED is PADN.
/FLT fault output
Open-drain output terminal to signal desaturation of conventional IGBTs or overcurrent of sense IGBTs.
Terminal /FLT is set low, if desaturation or overcurrent occurs. The /FLT terminal must be connected via a pull-
up resistor to PADP.
The reference terminal for /FLT is GND1.
RDY1 ready status
Open-drain output to signal the proper operation of the input side. RDY1 is set to high if the input side terminals
VCC1 and PADP are above their respective undervoltage thresholds. The RDY1 terminal should be connected
a via pull-up resistor to PADP.
The reference ground terminal for RDY1 is GND1.
RDY2 ready status
Open-drain output to signal the proper operation of the output side. RDY2 is set to high, if the output side supply
is above the UVLO2 level and the internal chip data transmission is operating properly. The RDY2 terminal
should be connected via a pull-up resistor to PADP.
The reference ground terminal for RDY2 is GND1.
SIGI
I/O signature check input terminal (5 V, CMOS-compatible)
The reference terminal for SIGI is GND1.
