Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 1. θJA 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 to be measured with respect to GND, unless otherwise specified. Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application schematic. 9V < VD < 16V, RTD = 51.1kΩ, CT = 470pF, TA = -40°C to +105°C (Note 3), Typical values are at TA = +25°C PARAMETER TEST CONDITIONS MIN TYP MAX UNITS SUPPLY VOLTAGE Start-Up Current, IDD VDD < START Threshold - - 175 μA Operating Current, IDD RLOAD, COUTA,B = 0 - 2.89 - mA COUTA,B = 1nF - 5 8.5 mA UVLO START Threshold 5.9 6.3 6.6 V UVLO STOP Threshold 5.3 5.7 6.3 V Hysteresis -0.6 - V CURRENT SENSE Current Limit Threshold 0.55 0.6 0.65 V CS to OUT Delay (Note 4) - 35 - ns CS Sink Current 810 - mA Input Bias Current -1 - 1 μA PULSE WIDTH MODULATOR Minimum Duty Cycle VERROR < CT Offset - - 0 % Maximum Duty Cycle CT = 470pF, RTD = 51.1kΩ -94- % CT = 470pF, RTD = 1.1kΩ (Note 4) - 99 - % CT to SS Comparator Input Gain (Note 4) - 1 - V/V SS to SS Comparator Input Gain (Note 4) - 0.8 - V/V ISL6744A |
