Frequently Asked Questions
What is the input voltage range of the TPS2399DGKR?
The TPS2399DGKR operates from an input voltage range of -36V to -80V, with a nominal supply voltage of -48V. This makes it ideal for telecom and datacom applications that use standard -48V bus power distribution.
What package does the TPS2399DGKR use and what are its dimensions?
The TPS2399DGKR is housed in an MSOP-8 package (JESD-30 code: S-PDSO-G8), also referred to as Small Outline Package. This compact 8-pin surface-mount package is suitable for high-density PCB layouts in space-constrained telecom and industrial applications.
Does the TPS2399DGKR support adjustable overcurrent threshold?
Yes, the TPS2399DGKR features an adjustable threshold, allowing designers to set the overcurrent trip level using an external resistor. This flexibility enables precise protection tailored to the load current requirements of specific system designs.
What are typical applications for the TPS2399DGKR?
The TPS2399DGKR is commonly used in -48V hot swap controllers for telecom infrastructure such as ATCA shelves, CompactPCI backplanes, central office line cards, and datacenter power distribution units where boards must be inserted or removed without powering down the system.
Is the TPS2399DGKR RoHS compliant and what is its long-term availability?
Yes, the TPS2399DGKR is Pb-free (RoHS compliant, Pbfree Code: Yes) and has a YTEOL (Years To End Of Life) rating of 15, indicating Texas Instruments plans to support this part for at least 15 more years, making it a reliable choice for long-lifecycle telecom equipment.
