MEMS timing accelerates wireless charging says SiTime
For power-sensitive and space-constrained mobile and IoT applications, the SiT3901 uPower digitally controlled MEMS oscillator (DCXO) has been introduced by SiTime. It improves wireless charging speed by up to 25 per cent while reducing the overall timing solution area by up to 90 per cent, says the company. The MEMS oscillator is suitable for wireless charging systems for smart watches, activity trackers, hearing aids, and wearables.
Power Management IC charges wearables four times faster than competitors
Integrating a switching charger, the MAX77659 single inductor mode output (SIMO) power management IC (PMIC) from Analog Devices charges wearable devices and hearables four times faster than any other PMIC currently available.
