LTC4380 Overvoltage Protection
https://www.electronics-lab.com/ltc4380-overvoltage-protection/
Thomas Scherer @ elektormagazine.com writes: When it comes to protecting sensitive circuitry from potentially damaging over-voltage spikes and supply surges we usually resort to networks of coils, capacitors, resistors and suppression diodes to iron out the transients. The LTC4380 low quiescent current surge stopper IC from Linear Technology goes about it in a different way; […]
UsbSafe² – Programmable dongle for protecting USB devices from USB hosts and chargers
https://www.electronics-lab.com/usbsafe%c2%b2-programmable-dongle-protecting-usb-devices-usb-hosts-chargers/
USB connections can transfer both information and power. UsbSafe² is a device for protecting USB-connected hardware from both excessive voltage, current and unauthorized data access. Unfortunately, the practice of “juice jacking” (accessing data from a device connected to a public charging station), has become all too common. UsbSafe² provides a unique combination of an anti-juice […]
Single transistor provides short-circuit protection
https://www.electronics-lab.com/single-transistor-provides-short-circuit-protection/
Keith Szolusha@ edn.com writes: In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit may be insufficient protection to prevent a failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to the short circuit through the inductor and the catch diode. Regardless of current-limit protection in the IC, when a […]
