1ED44175N01B
25 V single-channel low-side gate driver with integrated over-current protection (OCP), fault reporting and enable functionality
EiceDRIVER™ 25 V single-channel low-side non-inverting gate driver IC for IGBTs with typical 2.6 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.
