Frequently Asked Questions
What negative supply voltage range does the TPS2393APWG4 support and how does that fit -48 V telecom equipment?
The TPS2393APWG4 supports a negative supply voltage range of -20 V to -80 V with a nominal operating point of -48 V, making it a direct fit for standard telecom power buses used in central-office and data-center equipment. This wide range also accommodates voltage droop during peak loads, ensuring reliable hot-swap operation across 1 channel without needing separate voltage-range components.
How should the adjustable overcurrent threshold be set on the TPS2393APWG4 for a 10 A load?
The TPS2393APWG4 uses an external sense resistor in series with the external FET to set the overcurrent threshold, typically around 50 mV to 100 mV sense voltage. For a 10 A load, a 5 mΩ to 10 mΩ sense resistor would generate the required trip voltage while minimizing power dissipation, offering a clean circuit-breaker response time under 1 µs. This single-channel implementation keeps the solution compact in the 14-pin TSSOP footprint.
When does TPS2393APWG4 make more sense than a fixed-threshold hot-swap controller in a -48 V design?
TPS2393APWG4 is preferred over fixed-threshold devices whenever the load current can vary across different system configurations or board revisions, because the adjustable threshold lets engineers program the 1-channel overcurrent trip point exactly to the load profile without stocking multiple part variants. Fixed-threshold controllers with a -48 V rating typically limit engineers to one current trip level and offer less flexibility for protection margins above 5 A or below 2 A.
