San Jose, Calif. Fairchild Semiconductor has introduced a self-oscillating, high-voltage gate driver (HVIC) that provides designers with a high performance and low-power solution for ballast, SMPS and half-bridge inverter designs. The FAN7387 is reportedly the industry's only HVIC with an external pin for dead-time control, aimed at greater design flexibility.
The FAN7387 HVIC is also designed with an innovative noise canceling technique and features high-side driver operation with negative Vs swings up to -9.8 V. This feature protects the IC from negative noise and makes it more noise immune, while alternate solutions must use an additional diode to achieve this same protection, Fairchild said.
All of Fairchild's HVICs, including the FAN7387, offer significant power savings due to their low quiescent current (220 uA) resulting in low-power consumption in standby mode. This HVIC also claims stable performance through its low temperature dependency and excellent system reliability over a wide range of operating conditions.
The FAN7387 uses lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's RoHS directive.
Pricing: $1.20 in quantities of 100.
Availability: Samples are available now. Delivery is eight weeks ARO.
