MAX622

The MAX622 is high-side power supplies, using a regulated charge-pump,generate a regulated output voltage 11V greater than the input supply voltage to power high-side switching and control circuits.The MAX622 allow low-resistance N-channel MOSFETs(FETs) to be used in circuits that normally require costly,less efficient P-channel FETs and PNP transistors.

Features of the MAX622 are:(1)+3.5V to +16.5V operating supply voltage range;(2)output voltage regulated to VCC +11V(Typ);(3)70A Typ quiescent current;(4)power-ready output.Applications of the MAX622 are:(1)high-side power control with N-channel FETs;(2)low-dropout voltage regulators;(3)power switching from low supply voltages;(4)H-switches;(5)stepper moto drivers;(6)battery-load management;(7)portable computers.

The absolute maximum ratings of the MAX622 can be summarized as:(1):the parameter is VCC,the rating is +17,the unit is V;(2):the parameter is VOUT,the rating is +30,the unit is V;(3):the parameter is IOUT,the rating is 25,the unit is mA;(4):the parameter is continuous total power dissipation (TA = +70) 8-pin plastic DIP (derate 6.9mW/ above +70),the rating is 552,the unit is mW;(5):the parameter is continuous total power dissipation (TA = +70) 8-pin SO (derate 5.88mW/ above +70),the rating is 471,the unit is mW;(6):the parameter is continuous total power dissipation (TA = +70) 16-pin plastic DIP (derate 7.4mW/ above +70),the rating is 593,the unit is mW;(7):the parameter is operating temperature range,the rating is 0 to +70,-40 to +85,the unit is ;(8):the parameter is storage temperature range,the rating is -65 to +160,the unit is ;(9):the parameter is lead temperature (soldering,10 sec),the rating is +300,the unit is .
