Prolonging battery life by up to four times longer than traditional low quiescent (Iq) LDOs, the MCP1811 is a linear low dropout (LDO) regulator available from Microchip. It enables reduced standby power consumption in remote, battery-powered sensor nodes and also enables faster response times and transient response for IoT, wearable and remote designs, says Microchip.

Wireless earbuds has auto-charge feature
Atwo-pin power and communications connection between earbuds and cradle has been developed by ams. The company introduces POW:COM, an interface technology which enables power and communication between a true wireless earbud and a charging cradle over a two-wire connection. A true wireless earbud previously required as many as six pins to provide both power transfer and communication between the charging cradle and the earbud, compromising the mechanical design of a small form factor that fits comfortably in the user’s ear.
Battery fuel-gauge ICs maximise run time for portables
Extending the run time of Lithium-Ion (Li-Ion) battery-powered mobile and portable devices such as wearables, electric bicycles, power tools and internet of things (IoT) products, the MAX17262 single-cell and MAX17263 single-/multi-cell fuel-gauge ICs are claimed to deliver the most accurate battery state-of-charge data in the industry, according to Maxim Integrated Products.
Microchip’s Bluetooth SoC combines Sony’s LDAC technology for audio devices
Today’s consumers expect Bluetooth audio devices to create an immersive and uninterrupted listening experience. Bluetooth audio designs, however, can be limited by the bit depth and frequency rate of existing codecs, the communication and compression technology used to send audio over the air. To bridge this divide, Microchip has developed a certified, Bluetooth 5-compliant system on chip (SoC) with Sony’s LDAC audio codec technology. Sony’s LDAC is considered the highest-quality audio codec available, reports Microchip. It transmits up to 990kbits per second data throughput, which is three times higher than the standard Bluetooth Sub-band Codec (SBC), and maintains frequency and bit depth of up to 96kHz/24-bit. The high compression and reproduction efficiency enables high-resolution audio listening experiences for Bluetooth audio devices, adds the company.
