Frequently Asked Questions
What is the maximum input voltage and current rating of the TPS25944ARVCT?
The TPS25944ARVCT supports an input voltage range of 2.7V to 18V and a continuous load current of up to 5A, making it suitable for a wide range of power bus voltages in industrial and computing applications.
Does the TPS25944ARVCT support adjustable overcurrent protection?
Yes, the overcurrent threshold is fully adjustable via an external resistor, allowing designers to set the trip point from well below 1A up to 5A to match the specific requirements of the protected load.
What package does the TPS25944ARVCT use and is it RoHS compliant?
The TPS25944ARVCT is housed in a 20-pin Quad Flat No-Lead (QFN) package with an R-XQCC-N20 JESD-30 code. It carries JESD-609 code e4, indicating full RoHS and lead-free compliance.
Can the TPS25944ARVCT be used as a replacement for a discrete eFuse plus external Schottky diode?
Yes, its integrated reverse current protection removes the need for an external Schottky diode, and the single-chip solution with 42mΩ RDS(on) MOSFET simplifies board layout while reducing total component count and BOM cost.
