What are the key features of TPS2034P?
- 2.2 A current limit with high-side MOSFET driver for controlled hot-swap insertion in 2.7 V to 5.5 V backplane systems
- Integrated overcurrent, thermal, and undervoltage lockout protection with fault reporting pin for system-level diagnostics
- Active-high enable control in a compact 8-pin DIP package for easy prototyping and industrial control board integration
What is TPS2034P used for?
TPS2034P is used in hot-swap power management circuits for telecom and networking line cards where boards must be inserted or removed from live backplanes without disrupting system operation. Its 2.7 V to 5.5 V operating range and 2.2 A current limit suit 3.3 V and 5 V PCIe, CompactPCI, and VME slot power management. The integrated fault reporting enables supervisory microcontrollers to detect insertion faults, overcurrent events, or thermal shutdown conditions in real time.

Frequently Asked Questions
What current limiting level does TPS2034P enforce and how does it protect downstream loads during hot insertion?
TPS2034P limits inrush and fault current to 2.2 A maximum during hot-swap insertion into a live 2.7 V to 5.5 V backplane. This prevents voltage rail collapse on the backplane bus while allowing the inserted board's bulk capacitors to charge in a controlled manner, protecting both the backplane supply and the newly inserted card.
What fault conditions does TPS2034P detect and report through its fault output pin?
TPS2034P monitors three fault conditions: overcurrent above 2.2 A, thermal shutdown triggered when junction temperature exceeds safe limits, and undervoltage lockout when the supply falls below approximately 2.7 V. The active-low fault output pin alerts the host microcontroller within microseconds, enabling rapid system-level fault response.
How does TPS2034P compare to TPS2033P in hot-swap controller selection?
TPS2034P uses an active-high enable signal while TPS2033P uses an active-low enable, allowing direct interfacing to different logic levels without an inverter. Both share the 2.2 A current limit, 2.7 V to 5.5 V operating range, and 8-pin DIP package, so the choice depends solely on the host controller's GPIO polarity.
Is TPS2034P in a DIP-8 package appropriate for production designs or mainly for prototyping?
The 8-pin DIP (PDIP-T8) package of TPS2034P suits through-hole prototype boards and low-volume industrial equipment where hand-assembly is common. For production designs requiring smaller footprints, Texas Instruments offers equivalent hot-swap controllers in SOT-23 or SOIC-8 surface-mount packages that save up to 70% board area.
