FEBFAN324x Evaluation Boards

Fairchild's FEBFAN324x Evaluation Boards are designed to evaluate any of the products in the FAN324x series, such as FAN3240 or FAN3241. The output of the FAN324x is rated for operation with supply rails from 8V to 60V. The filter / timer block prevents inadvertent switching from noisy input signals by providing input-pulse qualification (tQUAL) and maximum output pulse-width limit (tMAX). The FAN324x has two separate driver channels for the relay-open and relay-close signals needed to operate dual-coil relays. One enable/disable pin allows shutdown of both channels independent of the input signals. An internal thermal shutdown (TSD) function is provided for thermal protection. These FEBFAN324x evaluation boards use a two-layer Printed Circuit Board (PCB). The size of the board is designed to be small enough to be evaluated in confined spaces of the meter.

Fairchild 650V Field Stop IGBTs

Fairchild’s 650V Field Stop IGBT technology enables designers to develop a highly reliable system design with higher input voltage while offering optimum performance where low conduction and switching losses are essential. The 650V IGBTs feature high current handling capability, positive temperature coefficient, tight parameter distribution and a wide safe operating area. The increased breakdown voltage improves reliability where negative ambient temperatures are present; as the temperature decreases the IGBT and FRD blocking voltage also decreases making this device particularly beneficial for PV solar inverters used in colder climates. Because careful selection of IGBTs and free-wheeling diodes are essential for maximum efficiency, the 650V IGBT provides fast and soft recovery that reduces power dissipation and achieves low turn-on and turn-off losses.
