The 1ED44175N01B EiceDRIVER™ 25 V single-channel low-side non-inverting gate driver for MOSFET
and IGBT with typical 2.0 A source and sink currents in a tiny 6-lead PG-SOT23 package.

Over-current protection is typically implemented by a current measurement with a comparator and multiple
resistors and capacitors. 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 realizing best-in-class fault reporting accuracy with OCP threshold
tolerance of +/-5%. In addition, Infineon’s IC technology enables a tiny PG-SOT23 package by combining
the fault output and enable functions into a single pin.
