Fairchild Semiconductor's High Voltage Gate Driver ICs Provide Improved Noise Immunity and Performan

These devices provide improved noise immunity over competitive solutions Fairchild Semiconductor /quotes/comstock/13*!fcs/quotes/nls/fcs (FCS 9.05, +0.20, +2.26%) meets however these needs by offering designers new choices in high voltage gate drive ICs, including the FAN7392, a 2-input, 2-output / high and low side gate driver with shutdown function, the FAN7393, a 1-input, 2-output / half bridge with shutdown and controllable dead time, the FAN73932, a 1-input, 2-output / half bridge with shutdown and fixed dead time control and the FAN73933, a 2-input, 2-output / half bridge with controllable dead time.

These devices provide improved noise immunity over competitive solutions, and are part of the FAN739x series which features an innovative common-mode dv/dt noise canceling circuit that enables stable operation of the high voltage gate driver under high dv/dt noise circumstances. The devices also feature an advanced level shift circuit that offers high-side gate driver operation with negative VS swings of up to -9.8V (at VBS = 15V), where Vs is the high voltage floating supply return and VBS is the high side floating supply voltage.

Additionally, the FAN739x series provide stable operation over a wide temperature range of -40 deg to 125 deg C. The series also features floating channels for bootstrap operation to +600V, built-in under-voltage lockout however for VBS, and matched propagation delay for both channels. These devices also eliminate a buffer transistor when compared to other low current HVICs on the market.
