    Selecting TVS diodes in hot-swap and ORing applications

    Designers will often use a transient voltage suppression (TVS) diode to clamp large surge currents to a safe voltage level in order to protect nearby components from damage. In many ways, a TVS diode behaves like a Zener diode, but with a higher power-rating capability because of its larger die size and stronger wire bonding. Why do hot-swap applications...

    Fast and furious: designing longer-lasting 16S-17S Li-ion battery packs for e-motorcycles

    With the rapid growth in demand for delivery services, electric motorcycles (e-motorcycles) are becoming more popular as a transportation method because the battery capacity is much larger than e-bike/e-scooter batteries. More capacity enables longer ride times, which helps save time and enables longer-distance deliveries. An e-motorcycle battery...

    How to flexibly configure an LED driver for automotive headlights

    Electronic technology has advanced so that an electronic control unit (ECU) is required to control the functions of full LED automotive headlights. An ECU consists of mainly LED drivers for headlight functions such as high beams, low beams, daytime running lights, position lights, turn indicators and fog lights. In this article, I’ll explain the...

    Why signal isolation matters in 48-V HEV/EV systems

    One of the key differences between conventional internal combustion engine vehicles and hybrid electric vehicles (HEVs) or electric vehicles (EVs) is the presence of multiple batteries and voltage levels. Internal combustion engines operate from a single 12-V or 24-V battery, which is typically a lead acid battery. But HEVs and EVs use a secondary high...
