1ED44175 - low side gate driver
1ED44175 is an EiceDRIVER™ 25 V single-channel low-side non-inverting gate driver for IGBT with typical 2.6 A
source and sink currents in a tiny 6-lead PG-SOT23 package. 1ED44175N01B provides cost and space savings by
integrating the comparator. The new low-side gate driver utilizes Infineon's proprietary latch immune CMOS
technologies to enable a rugged monolithic construction while achieving best-in-class fault reporting accuracy
with an OCP threshold tolerance of +/-5%. Its features are listed as follows:
-0.246 V over current threshold with accurate ±5% tolerance
•
Over current detection with negative voltage input
•
Single pin for fault output and enable
•
Programmable fault-clear time
•
Under voltage lockout for IGBTs
•
CMOS Schmitt-triggered inputs
•
3.3 V, 5 V and 15 V input logic compatible
•
Output in phase with input
•
-10 Vdc negative input capability of OCP pin
•
3 kV ESD HBM
•
