High voltage gate driver ICs from Fairchild Semiconductor with improved noise immunity

Fairchild Semiconductor has released a set of high voltage gate drive ICs, which includes:
--FAN7392, a 2-input, 2-output / high and low side gate driver with shutdown function
--FAN7393, a 1-input, 2-output / half bridge with shutdown and controllable dead time
--FAN73932, a 1-input, 2-output / half bridge with shutdown and fixed dead time control
--FAN73933, a 2-input, 2-output / half bridge with controllable dead time.

Fairchild claims these driver ICs which can work without buffer transistor 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.

The series also features floating channels for bootstrap operation to +600V, built-in under-voltage lockout for VBS, and matched propagation delay for both channels.

Other devices in the series include the FAN7390 (2-input, 2-output / high & low side gate driver), and the FAN73901 (2-input, 2-output/ high & low side gate driver). Available in 8-pin DIP, 8-pin SOP, 14-pin SOIC and 16-pin SOIC packages, devices in the series are pin-compatible with existing solutions.

Some of the suggested applications for these driver chips include motor drive inverters, distributed power supplies and telecom system power supplies.

Operating temperature range: -40° to 125°C.
