Self-Heating Sensor Chip
These heater sensor chips use platinum on alumina and oxidized silicon. Applications include determination of thermal resistance of IC chips, variable optical attenuation of arrayed wave-guide gratings, and thermal management in miniature chambers. The TM365 has two thermal sensors close to the heater for stringent temperature control. The TM364 single sensor offers a design with moderate temperature control.

Intelligent Power Switch
Fairchild's FDC6901L, the first intelligent power switch combining a low-current IC and P-Channel MOSFET for slew rate control up to 3 A, is an ideal load switch for portable electronics. The device provides three programmable slew rates and adjustable inrush current for superior power management and performance, and comes in a TSOP-6 (SuperSOT-6) package for high-volume surface mount applications.

Current Sensing Resistors
The LM Series is for high nominal power and high-pulse power applications. The etched-foil technology uses a low tcr alloy resistor element, resulting in long-term stability at full rated load and 140°C, while keeping inductance to less than 10 nH. The tcr for a 1-mΩ resistor is less than 50 ppm/°C. Available in three EIA standard sizes: 2512 (LMS); 2010 (LMP) and 1206 (LMK), these packages are rated from 0.5 W (LMK) to 2 W (LMS).

Powerex has expanded its line of high current devices by adding 1200-A, 1600-A, 1800-A and 2400-A ratings to its family of 1700-V IGBT products. This is believed to be the widest range at 1700-V in the industry as it begins at 50. They are targeted for high-power inverter applications for utility interface, 690-Vac motor drives and light-rail applications.
