Fairchild Semiconductor Releases New SPM Series

May 16, 2002 by Jeff Shepard

Fairchild Semiconductor International (San Jose, CA) introduce a new series of smart power module (SPM) products in compact, dual in-line packages (DIP) that provide adjustable-speed motor drive control and fully integrated circuit protection for ac motors found in appliance applications such as washing machines and air conditioners.

Compared to discrete IGBT solutions, the integrated SPM requires less than half the board space, while providing low-voltage control and a high-voltage output stage rated at 10A to 20A at 230Vac. The DIP-SPM comes in a small (60mm x 31mm), ceramic-based transfer molded-type package that optimizes heat transfer from the IGBTs, achieving a 27-percent-higher power rating than a conventional TO-220F package. The high-speed, high-voltage control circuit built into the module eliminates the need for opto-couplers and allows the IGBTs to be driven by a single bias supply. In addition, the advanced current-sensing IGBT chips provide short-circuit current detection and protection.

Other features of the DIP-SPM products include built-in, high- and low-speed controls for user-flexibility. Full protection features ensure reliability, including an optional built-in thermistor for over-temperature monitoring. For advanced current sensing, IGBT chips on the module maintain continuous monitoring of the IGBT current for short-circuit current detection. Divided negative dc-link terminals provide inverter current sensing.

Samples are available now. Pricing ranges from $15 to $19 for 1,000-piece quantities. Delivery is 12 weeks or more for larger orders.
