Chipscale MOSFETs Plus Analog Switch Rated At 1.8V

Additions to the company’s line of Micro Foot devices claim to break ground as the first chipscale MOSFETs and analog switch rated for 1.8V operation. Measuring 1.6 mm x 1.6 mm x 0.65 mm, the Si8405DB p-channel power MOSFET has a breakdown voltage of 12V and an on-resistance from 55 m_ at -4.5V gate drive to 90 m_ at -1.8V. With a drain-to-source voltage of 20V, the Si8401DB single p-channel device has a maximum on-resistance of 65 m_ at -4.5V or 95 m_ at -2.5V. Measuring 1.07 mm x 1.57 mm x 0.7 mm, the DG3000 analog switch provides a charge injection of 5 pC, an on-resistance of 1.4_, and can operate with frequencies beyond 100 MHz. Pricing for the Si8405DB and Si8401DB MOSFETs is $0.36 each/100,000 and for the DG3000 is $0.47. VISHAY INTERTECHNOLOGY INC., Malvern, PA. (610) 644-1300.
