The 3 V to 20 V supply range covers common backplane voltages from 3.3 V up to 12 V and 24 V nominal rails, though the 20 V ceiling means a 24 V rail with tolerance above 20 V needs a different part. Programmable current limit and fault timeout let you set the inrush profile to match the downstream capacitance — a 1000 µF bank at 12 V ramps up at a controlled rate rather than tripping the circuit breaker on the backplane. The latched fault behavior means the part stays off after an overcurrent event until the input is cycled, which suits applications where automatic retry could cause repeated stress. ## Package thermal considerations at 6 A The 8-PowerSOIC package with exposed PowerPad (supplier device package 8-SO PowerPad) is designed to conduct heat from the die through the pad into the PCB copper. Without adequate thermal management, the thermal limit protection will cycle the output.","metaTitle":"TPS2421-1DDAR Hot Swap Controller, 6A, 3-20V, 8-SO PowerPad","metaDescription":"Texas Instruments TPS2421-1DDAR hot swap controller, 6A max output, 3V-20V supply, -40°C to 125°C, active production, ROHS3 compliant.
