Vitality harvesting PMIC supplies wi-fi connectivity

Telink’s TLSR8273-M-EH supplies low-power wi-fi connectivity, vitality autonomy, and energy administration in a compact 23×21-mm module. The half combines Telink’s multiprotocol wi-fi connectivity SoC with Nowi’s vitality harvesting PMIC to make batteryless operation potential for a variety of IoT functions.

With its multiprotocol radio, 32-bit MCU, and embedded reminiscence, the TLSR8273-M-EH helps varied requirements within the 2.4-GHz ISN band, together with Bluetooth LE 5.1, Bluetooth mesh, IEEE 802.15.4, Zigbee, RF4CE, 6LoWPAN, and Thread. It additionally has a PTA {hardware} interface for Wi-Fi coexistence. The module works with varied sorts of rechargeable batteries utilizing an onboard USB charger or the vitality harvester. Alternatively, the vitality harvester can be utilized with supercapacitors to make finish units batteryless.

The module is suitable with Telink’s software program growth kits, permitting prospects to improve their merchandise with minimal effort. One utility for the TLSR8273-M-EH is in tv distant controls that harvest vitality from indoor lighting utilizing a PV cell. A reference design based mostly on the TLSR8273-M-EH is offered for such distant management merchandise.

Samples of the TLSR8273-M-EH wi-fi connectivity module can be found now.
