Holtek is pleased to announce the release of its new power bank dedicated Flash MCUs, the BP45F4NB and BP45FH4NB. Using their internal complementary PWM drive function, the devices can implement full charge and discharge battery management operations...
Why do you never see birds on high-tension power lines?
We very often see flocks of birds perched in trees, on rooftops, on local power line wires, and even on radio antennas. However, I have noticed that I never see birds coming to rest on high-tension power lines...
Nexperia extends LFPAK56D MOSFET line-up with AEC-Q101-qualified half-bridge package
Nexperia announced a series of half-bridge (high side & low side) automotive MOSFETs constructed in the space-saving LFPAK56D package format. The half-bridge configuration of two MOSFETs is a standard building block for many automotive applications including motor drives and DC/DC converters...
