Frequently Asked Questions
How many independent hot swap channels does the TPS2346PWRG4 control simultaneously?
The TPS2346PWRG4 controls 4 independent hot swap channels simultaneously. Each channel provides its own overcurrent and overvoltage protection, making it efficient for managing up to 4 power rails on a single board. This 4-channel architecture reduces component count compared to using discrete single-channel controllers.
What is the operating temperature range of the TPS2346PWRG4 and which environments does it suit?
The TPS2346PWRG4 operates over a commercial temperature range of 0°C to 70°C. This makes it suitable for indoor optical network equipment, telecom central office hardware, and server-room infrastructure where ambient temperatures are controlled. Industrial or automotive environments requiring -40°C operation would need a different variant.
Which package does TPS2346PWRG4 use and how does its footprint affect PCB layout in dense designs?
TPS2346PWRG4 uses a 24-pin TSSOP (Thin Shrink Small Outline Package) with a compact footprint measuring approximately 7.8 mm × 4.4 mm. This small outline enables high-density PCB layouts in 1U rack-mount cards and multi-channel optical line modules where board space is at a premium.
Is TPS2346PWRG4 compliant with RoHS and halogen-free requirements for modern regulatory standards?
Yes, TPS2346PWRG4 carries JESD-609 Code e4, indicating it is a lead-free and RoHS-compliant device. The plastic-epoxy package body meets halogen-free construction standards. This compliance is essential for equipment sold in the EU, China, and other markets enforcing environmental directives on electronic components after 2006.
When would TPS2346PWRG4 be preferred over a single-channel hot swap controller for an optical network card?
TPS2346PWRG4 is preferred when a board requires protection on 4 supply rails (for example, +5 V, +3.3 V, +1.8 V, and -5.2 V) because integrating 4 channels in one 24-TSSOP device saves approximately 3 additional ICs and reduces PCB area by over 60% compared to using four separate single-channel controllers.
