(2) All typical values are at TJ = 25°C. CURRENT-SENSE SECTION ELECTRICAL CHARACTERISTICS VCC = 15 V (1), R T = 10 kΩ, CT = 3.3 nF, over recommended operating free-air temperature range (unless otherwise specified) TL284xB PARAMETER TEST CONDITIONS UNIT MIN TYP(2) MAX Voltage amplification(3) (4) 2.85 3 3.15 V/V Current-sense comparator threshold(3) COMP = 5 V 0.9 1 1.1 V Supply-voltage rejection ratio(3) VCC = 12 V to 25 V 70 dB Input bias current –2 –10 μA Delay time to output(5) VFB = 0 V to 2 V 150 300 ns (1) Adjust VCC above the start threshold before setting it to 15 V. (2) All typical values are at TJ = 25°C. (3) Measured at the trip point of the latch, with VFB at 0 V. (4) Measured between ISENSE and COMP, with the input changing from 0 V to 0.8 V. (5) Specified by design. Not production tested. Copyright © 2010–2012, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s): TL2843B-Q1 |
