Frequently Asked Questions
What input voltage range does the TPS2392PWG4 support?
The TPS2392PWG4 supports a wide negative input supply range of -20 V to -80 V, with a nominal operating voltage of -48 V. This range covers standard telecommunications power bus specifications including variations in -48 V systems encountered in central office, DSLAM, and network infrastructure equipment.
What is the purpose of the hot swap controller function in the TPS2392PWG4?
The hot swap controller function in the TPS2392PWG4 allows circuit boards to be safely inserted into or removed from a live -48 V power bus without causing voltage glitches or damaging supply rails. It controls an external FET to limit inrush current during board insertion and provides overcurrent protection during normal operation.
Does the TPS2392PWG4 have an adjustable overcurrent threshold and how is it set?
Yes, the TPS2392PWG4 features an adjustable overcurrent threshold, allowing designers to set the current limit via an external sense resistor or resistor divider. This flexibility accommodates different load requirements and cable impedances across various -48 V telecom and industrial power applications.
What package does the TPS2392PWG4 use and is it RoHS compliant?
The TPS2392PWG4 is housed in a 14-pin TSSOP package (JESD-30 code R-PDSO-G14) with a plastic/epoxy body, suitable for standard surface-mount PCB assembly. It is RoHS compliant with a JESD-609 code of e4, confirming it meets lead-free environmental standards.
What are the typical applications for the TPS2392PWG4?
The TPS2392PWG4 is commonly used in -48 V telecommunications infrastructure including DSL line cards, VoIP gateway boards, router line cards, and central office equipment requiring live board insertion capability. It is also applicable in industrial -48 V power distribution systems and negative-rail instrumentation where adjustable overcurrent protection and hot swap control are needed.
