ABSOLUTE MAXIMUM RATINGS (TA = 25oC) Characteristic Symbol Value Unit Supply Voltage Operating Temperature Storage Temperature Output Current VCC -0.3 ~ +8.0 V Topr -10 ~ +70 oC Tstg -40 ~ +125 oC IO 30 mA * Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2011, February, Rev. 01 IL75XX ELECTRICAL CHARACTERISTICS (TA = 25oC, unless otherwise specified) Characteristic Supply Voltage Symbol VCC Detecting Voltage VDET Supply Current Low Output Voltage High Output Voltage Hysteresis Voltage Detective Voltage Temperature Coefficient ICC VOL VOH VHYS VDET T  VDET Test Conditions VCC = 5.0V, No Load VCC = VDET–0.2V, IOL = 0.1mA VCC = VDET+0.2V, IOH = 0.1mA -10oC < TA <70oC Min 1.2 2.16 2.35 2.50 2.65 2.74 3.23 3.82 4.12 4.61 4.90 VCC – 0.3V Typ 2.20 2.40 2.55 2.70 2.80 3.30 3.90 4.20 4.70 5.00 8 0.1 2.0  0.02 Max 5.5 2.24 2.45 2.60 2.75 2.86 3.37 3.98 4.28 4.79 5.10 15 0.3 Unit V V A V V % %/oC BLOCK DIAGRAM CMOS OUTPUT VCC RA VB + RB VREF RC VCC OUT VSS OPEN DRAIN OUTPUT RA VB RB RC + - VREF OUT VSS FUNCTIONAL DESCRIPTION The IL75XX series is the set of voltage detectors equipped with a high stability voltage reference which is connected to the negative input of a comparator denoted as VREF in block diagram. When the voltage drop to the positive input of the comparator (VB) is high than VREF, VOUT goes high. If VCC is decreased so that VB falls to a value less than VREF, the comparator output inverts from high to low, VOUT goes low. The device has hysteresis to prevent the circuit from oscillation when VB  VREF. If VCC falls below the minimum operating voltage, the output becomes undefined. The detectable voltage is defined as: VDET    RARBRBRCRCVREF The release voltage is defined as:   RARB VDET   RB  VREF The hysteresis width is: VHYS  VDET ()  VDET () 2011, February, Rev. 01 ELECTRICAL CHARACTERISTICS 1.
