Real Time IC Clock Power Back-up

Over 1 billion real time clock (RTC) ICs are being sold each year with the ability to keep time when power fails. Clock chip manufacturers have been steadily lowering operating currents, which are now approaching 100 nA. This allows the use of Cymbet EnerChip rechargeable solid state batteries rechargeable solid state batteries as a replacement for traditional, bulkier power sources, such as coin cell batteries and super capacitors. The EnerChip can provide power from a few hours to a few weeks and can be recharged thousands of times. They offer the engineer new cost-lowering possibilities, such as reduced size, Pb-free reflow tolerance and automatic pick & place assembly methods.
