Article Type: New products From: Microelectronics International, Volume 28, Issue 1
High Current Driving HVIC Solutions for Motor, Industrial Applications.
Power engineers designing motor and industrial applications such as motor drive inverters, distributed power supplies and telecom system power supplies, need a high voltage gate driver solution that provides improved noise immunity and increased performance, while being pin-compatible to solutions currently available.
Fairchild Semiconductor meets these needs by offering designers new choices in high-voltage gate drive integrated circuits (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 cancelling 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 V S swings of up to −9.8 V (at V BS=15 V), where V S is the high voltage floating supply return and V BS is the high side floating supply voltage.
Additionally, the FAN739x series provide stable operation over a wide temperature range of −40°C to 125°C. The series also features floating channels for bootstrap operation to+600 V, built-in under-voltage lockout for V BS, and matched propagation delay for both channels. These devices also eliminate a buffer transistor when compared to other low current HVICs on the market.
Other devices in the series include the FAN7390 (2-input, 2-output/high and low side gate driver) and the FAN73901 (2-input, 2-output/high and 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, making it an easy replacement in any design or component.
