RTC baner vej for MLCC kondensatorer som batteri backup
Micro Crystal lancerer temperaturkompenseret RTC, der med ultralavt effektforbrug gør det muligt at erstatte dyre batterier og supercaps med prisbillige MLCC kondensatorer i forbindelse med batteri backup i nogle applikationer (in english).
The RV-8803-C7 from Micro Crystal is the first temperature compensated RTC optimized for ultra-low power consumption. The current consumption of 240nA and operation down to 1.5V significantly increases the operational life of backup supplies and allows for potential use of low cost MLCC capacitors as a short term backup solution as replacement for expensive batteries and supercaps. All this while providing accuracy of ±3.0 ppm (±0.26 seconds/day) over a temperature range of -40° to +85°C. In addition to the lowest current and best accuracy of all temperature-compensated RTCs, the RV-8803-C7 also has the smallest ceramic package in the industry with an integrated 32.768 KHz quartz crystal.
The RTC’s accurate timekeeping together with reliability of a power failure backup makes it ideal for a wide range of applications such as metering applications, embedded modules, data loggers, white goods, automotive, portable/wearable medical equipment and all types of POS systems.
