10 / 14 page that swings above VREF voltage for positive-sense volt- ages and below VREF for negative-sense voltages. VOUT is equal to VREF when VSENSE is equal to zero. Set the full-scale output range by selecting RSENSE and the appropriate gain version of the MAX4080/ MAX4081. 76V, High-Side, Current-Sense Amplifiers with Voltage Output 10 ______________________________________________________________________________________ MAX4081T VSENSE ICHARGE ILOAD RSENSE VCC GND RS+ RS- OUT REF1A REF1B 5V SYSTEM LOAD AND CHARGER BATTERY VOUT = GND VOUT = 10V VREF1A = VREF1B = 5V DISCHARGE CURRENT 4.5V TO 76V CHARGE CURRENT 5V 10V -250mV 250mV -5V VSENSE Figure 1.
