ZMD ZLED7012 and ZLED7022 LED Control ICs

ZMDI announced the ZLED7012 and ZLED7022 LED control ICs. The ZLED7012 and ZLED7022 feature low-noise, constant-frequency charge pump DC/DC converters that can efficiently drive up to four (ZLED7012) or six (ZLED7022) strings of LEDs. The ZLED7012 and ZLED7022 come in a 12-pin UTQFN package (2mm x 2mm). The ZLED7012 is priced at €0.32 and the ZLED7022 is priced at €0.39. Both parts are available in mass production now. Full application kits, application notes, and an evaluation board are also available now.

Microchip RE46C162/3 Ion, RE46C165/6/7/8 Photo Smoke Detector ICs

Microchip Technology introduced the RE46C162/3 Ion and RE46C165/6/7/8 (RE46C16X) photo smoke-detector ICs with alarm memory. RE46C16X ICs feature alarm memory, which enables the ICs to quickly determine which detector in an interconnected loop triggered an alarm. A charge-dump feature allows the alarm on all interconnected devices to stop sooner. The ICs’ low energy use enables smoke detectors with a battery life of 10 years, and an interconnect filter enables a connection to other devices, such as CO detectors.
