6V Lithium Ion Battery Protection s 5-pin SOT23 Package DESCRIPTION The SP6828/6829 devices are CMOS Charge Pump Voltage Inverters that can be implemented in designs requiring a negative voltage from a +3V battery source.
The SP6828/ 6829 devices are ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 20µA for the SP6828 and 40µA for the SP6829.
Both devices can output 25mA with a voltage drop of 500mV.
These devices combine a low quiescent current with high efficiency (>95% over most of its load-current range), which is ideal for designs using +3.
3V or +3.
6V lithium ion batteries.
Applications include cell phones, PDAs, medical instruments and other portable equipment.
The SP6828/6829 devices are available in a space-saving 5-pin SOT23 Package.
