MicroFET MOSFETs extend battery life in consumer devices

Fairchild Semiconductor has introduced dual N-Channel and single N-Channel MOSFETs that aare designed to extend battery life in applications such as cellular handsets, electric toothbrushes and shavers.

Packaged in thermally enhanced 2 mm x 2 mm x 0.8 mm MicroFET MLP packaging, ideal for space-constrained applications, the FDMA1024NZ and FDMA410NZ devices offer ultra-low RDS(ON) to conserve battery life. The efficient MicroFET MOSFETs have been created to address the power challenges of today's feature-rich portable applications.

The FDMA410NZ offers portable designers the industry's lowest RDS(ON) of 23 mOhms at 4.5 V, in slim 2 mm x 2 mm packaging. Both of these products provide guaranteed RDS(ON) ratings with VGS values as low as 1.5 V, making them ideal for lithium ion or primary cell battery applications.

Fairchild's advanced-performance PowerTrench MOSFET process technology yields exceptionally low values for RDS(ON) , total gate charge (QG) and Miller Charge (QGD) – enhancements that result in superior switching performance and thermal efficiencies.

Fairchild Semiconductor offers the industry's broadest portfolio of 2 mm x 2 mm thermally enhanced ultra-compact, low-profile devices targeting low-power applications. These easy-to-implement, high-performance and space-saving MOSFETs are ideal for low-voltage switching, power management and battery charging systems.
