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. +150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Constantly operated at +150°C may shorten the life of the part. NOTES: 1. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Technical Brief TB379 for details. 2. All voltages are with respect to GND. Electrical Specifications ISL884xAA - Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application schematic onpage 3 and page 4. VDD = 15V, RT = 10kΩ, CT = 3.3nF, TA = -40 to +105°C (Note 3). Typical values are at TA = +25°C PARAMETER TEST CONDITIONS MIN TYP MAX UNITS UNDERVOLTAGE LOCKOUT START Threshold (ISL8840A, ISL8841A) 6.5 7.0 7.5 V START Threshold (ISL8843A, ISL8845A) 8.0 8.4 9.0 V START Threshold (ISL8842A, ISL8844A) (Note 6) 13.3 14.3 15.3 V STOP Threshold (ISL8840A, ISL8841A) 6.1 6.6 6.9 V STOP Threshold (ISL8843A, ISL8845A) 7.3 7.6 8.0 V STOP Threshold (ISL8842A, ISL8844A) 8.0 8.8 9.6 V Hysteresis (ISL8840A, ISL8841A) - 0.4 - V Hysteresis (ISL8843A, ISL8845A) - 0.8 - V Hysteresis (ISL8842A, ISL8844A) - 5.4 - V Startup Current, IDD VDD < START Threshold - 90 125 μA Operating Current, IDD (Note 4) - 2.9 4.0 mA Operating Supply Current, ID Includes 1nF GATE loading - 4.75 5.5 mA REFERENCE VOLTAGE Overall Accuracy Over line (VDD = 12V to 30V), load, temperature 4.925 5.000 5.050 V Long Term Stability TA = +125°C, 1000 hours (Note 5) - 5 - 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 ISL8840A, ISL8841A, ISL8842A, ISL8843A, ISL8844A, ISL8845A |
