This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 2. All voltages are with respect to GND. Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application schematic. VDD = 15V (Note 6), Rt = 10kΩ, Ct = 3.3nF, TA = -40 to 105 oC (Note 3), Typical values are at TA = 25 oC PARAMETER TEST CONDITIONS MIN TYP MAX UNITS UNDERVOLTAGE LOCKOUT START Threshold (ISL6843, ISL6845) 7.8 8.4 9.0 V START Threshold (ISL6842, ISL6844) 13.3 14.3 15.3 V STOP Threshold (ISL6843, ISL6845) 6.7 7.2 7.7 STOP Threshold (ISL6842, ISL6844) 8.0 8.8 9.6 V Hysteresis (ISL6843, ISL6845) - 0.8 - V Hysteresis (ISL6842, ISL6844) - 5.4 - V Start-Up Current, IDD VDD < START Threshold - 60 100 µA Operating Current, IDD (Note 4) - 3.3 4.0 mA Operating Supply Current, ID Includes 1nF GATE loading - 4.1 5.5 mA REFERENCE VOLTAGE Overall Accuracy Over line (VDD = 12V to 18V), load, temp 4.925 5.000 5.050 V Long Term Stability TA = 125 oC, 1000 hours (Note 5) - 5 - mV Fault Voltage 4.40 4.65 4.85 V VREF Good Voltage 4.60 4.80 VREF-0.05 V Hysteresis 50 165 250 mV Current Limit, Sourcing -20 - - mA Current Limit, Sinking 5- - mA CURRENT SENSE Input Bias Current VCS = 1V -1.0 - 1.0 µA CS Offset Voltage VCS = 0V (Note 5) 95 100 105 mV COMP to PWM Comparator Offset Voltage VCS = 0V (Note 5) 0.80 1.15 1.30 V Input Signal, Maximum 0.91 0.97 1.03 V ISL6842, ISL6843, ISL6844, ISL6845 |
