The MAX1822 high-side supply, using a regulated charge pump, generates a regulated output voltage 11V greater than the input supply voltage to power high-side switching and control circuits. The MAX1822 allows low-resistance N-channel MOSFETs (FETs) to be used in circuits that normally require costly, less efficient P-channel FETs and PNP transistors. The high-side output also eliminates the need for logic FETs in +5V and other low-voltage switching circuits.
A +3.5V to +16.5V input supply range and a typical quiescent current of only 150µA make the MAX1822 ideal for a wide range of line- and battery-powered switching and control applications where efficiency is crucial. Also provided is a logic-level power-ready output (PR) to indicate when the high-side voltage reaches the proper level.
The MAX1822 comes in an 8-pin SO package and requires three inexpensive external capacitors. The MAX1822 is a pin-for-pin replacement to the MAX622.
