1EDN7550UXTSA1

EiceDRIVER 1EDNx550 is part of the TDI family of single-channel highside and low-side gate driver ICs. The TDI family has a fully differential input circuitry. The truly differential inputs (TDI) provide excellent common-mode robustness (CMR) and eliminates the risk of false triggering. The small package footprints enable versatile layout in both low-side and high-side driving. EiceDRIVER 1EDNx550 is a family of high-side and low-side non-isolated gate drivers whose application ranges into fields usually reserved for isolated and level shifter drivers, resulting in significant cost benefits. This is made possible by the unique truly differential input (TDI) stage concept. The TDI input stage allows controlling the driver even if a common-mode voltage is present on the input differential pair. Common-mode voltages up to ±200 V DC and ±400 V AC peak between ground reference (GND) and driver inputs (IN+, IN-) are possible. EiceDRIVER 1EDNx550 is suited for any application with unwanted voltage shifts between driver and system ground and in high-side driving within the allowed static common-mode range (±200 V max.). Switches requiring a bipolar driving voltage can be operated easily as well, taking advantage of the common mode voltage handling capability of the TDI.
