NFC charging transmitter offers high output for small consumer devices
Panthronics has increased system efficiency by 18 per cent in its transmitter design for the PTX130WNFC charging transmitter. It is claimed to be the industry’s highest output power for faster NFC charging. It is based on sine wave architecture to offer simpler antenna matching, a smaller bill of materials (BoM) and high tolerance of antenna misalignment.
Charger IC is wireless power transfer-compatible
A multi-functional, compact charging IC for lithium-ion (Li-ion) batteries, the XC6810, supports wireless power transfer.
LTE-M and NB-IoT module
Industrial IoT, connected or smart agriculture, logistics and smart metering applications can use the Adrastea-I module by Würth Elektronik. The low power, multi-band LTE-M and NB-IoT module measures just 13.4 x 14.6 x 1.85mm but integrates GNSS, an Arm Cortex M4 and 1Mbyte flash memory which is reserved for user application development.
