25 V single-channel low-side gate driver with integrated over-current protection (OCP), fault reporting and enable functionality
Over-current protection is typically implemented by a current measurement with a comparator and multiple resistors and capacitors. 1ED44176N01F 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 small PG-DSO8 package by combining the fault output and enable functions into a single pin.
