Load switches’ low IQ extend battery device lifetimes
Three load switches released by Toshiba Electronics Europe, deliver a decrease in quiescent current (IQ) which extends the operating life of wearables and IoT devices that are powered by small batteries.
Zener diodes prolong battery time and save PCB space
Low current regulator diodes are available from Nexperia in three surface mount package options. The 50 microA Zener diodes are available in three surface mountable package options: SOT23 (BZX8450), SOD323 (BZX38450) and SOD523 packages (BZX58550) and leadless DFN1006BD-2 (BZX8850S) package.
Wireless charger modules optimise antenna layout for thin devices
Compact wireless charger modules with an integrated antenna board allow developers to add wireless power supply functionality to smaller devices such as smart tags/cards or PC peripherals. The BP3621 (transmitter) and the BP3622 (receiver) are available from Rohm Semiconductor.
