DESCRIPTION

The SP6830/6831 devices are CMOS Charge Pump Voltage Inverters that can be implemented into designs which require a negative voltage from a battery voltage source as low as +1.15V or a power supply rail voltage as high as +5.3V. The SP6830/6831 devices are ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 70μA for the SP6830 and 200μA for the SP6831. These devices combine an ultra-low shutdown current of 95 over most of its load-current range) which are ideal for designs using batteries such as cell phones, PDAs, medical instruments, and other portable equipment. The SP6830/6831 devices are available in a space-saving 6-pin SOT23-6 Package.
