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...

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...

Get more out of your power supply with port power management

With the publication of the new Institute of Electrical and Electronics Engineers 802.3bt standard, the power range of Power over Ethernet (PoE) loads continues to expand. If you are designing systems that provide PoE, this presents a challenge. You may need to provide 5 W of power to a low-end Internet Protocol camera or 70 W to a high-end wireless...

Powering tiny industrial automation control equipment with high-voltage modules: how to ensure reliability

It’s not unusual to find industrial automation control equipment like field sensors (for proximity, pressure, flow or temperature, for example) housed in increasingly inconspicuous packages. Figure 1 shows an example of a proximity sensor housed in a tiny screw (which can be as small as 8 mm or in some instances even smaller). While the electronics...
