FAD8253MX

The FAD8253MX is a monolithic half-bridge gate driver IC designed for driving high-voltage, high-speed IGBTs up to 1200V. It features a peak output current capability of 2.5A source and 3.4A sink, with a supply voltage range of 4.5V to 18V. The driver operates within an ambient temperature range of -40°C to 125°C.

This gate driver incorporates ON Semiconductor's high-voltage process and common-mode noise canceling technique for stable operation under high dv/dt noise conditions. It includes UVLO circuits optimized for IGBT thresholds for both high-side and low-side outputs, and a built-in low-side current detection circuitry with soft shutdown for overcurrent or short-circuit protection. The FAD8253MX is supplied in a 14-SOIC package suitable for surface mounting.

Key electrical specifications include independent channel type, non-inverting input, and IGBT gate type. It offers matched propagation delays and built-in shoot-through prevention logic with a typical dead time of 120 ns. The device also provides fault reporting during overcurrent or short-circuit conditions and an external shutdown pin for disabling driver outputs.

Applications for the FAD8253MX include high-voltage auxiliary motor drives, generic half-bridge and full-bridge drivers, on-board chargers, DC/DC converters, and traction inverters.
