Here is a detailed view of reverse polarity protection circuits for safeguarding battery-connected automotive systems.

A new family of P-channel MOSFETs provides performance similar to N-channel MOSFETs, including fast switching and reverse polarity operation. The source voltage of a P-channel device is stationary ...

N-channel MOSFETs turn on when a positive voltage is applied to the gate relative to the source. P-Channel MOSFET (PMOS): Less common than NMOS, P-channel MOSFETs have a majority carrier current ...

A family of 150-V and 200-V p-channel power MOSFETs in SC-70 and SOT-23 packaging saves space in primary-side active-clamp circuits in dc-dc converters. Until now, the p-channel MOSFETs for active ...

ROHM has released a 24-model lineup of -40V/-60V withstand voltage P-channel MOSFETs available in both single and dual configurations. The growing demand for higher efficiency and power density is ...

P-channel MOSFETs can simplify designs when you use them as high-side switches on circuits with voltages exceeding 100V dc. When driving a MOSFET, you must rapidly charge and discharge the input ...

CMOS, which means Complementary Metal Oxide Semiconductor, is based on combining two polarities of MOSFETS ... and how it affects the device: An N-Channel device is activated when a positive ...

Toshiba has introduced a 60V p-channel mosfet rated at 60V and 90A continuous current, with AEC-Q101 qualification for automotive use. Called XPH8R316MC (90A), the company sees it being used in ...

Built using TrenchFET silicon technology, the Siliconix P-channel MOSFETs suit load, power-amplifier, and battery switching. The 2.05×2.05-mm PowerPak SC-70 package provides a 29-mΩ maximum ...

Both devices are rated for a drain-source voltage (VDSS) of -60V and are capable of operating at channel temperatures (Tch) up to 175ºC. The maximum drain-source on-resistance (RDS(ON)) of the ...
