TPS2514ADBVR

TPS2514ADBVR is a TI single‑channel hot‑swap/load switch with programmable current limit and protections. It places a high‑side MOSFET in series with the load and controls inrush, enabling safe power‑up for boards and power distributions.
Key features (typical):
- Adjustable current limit via ISET resistor
- Soft‑start to limit inrush
- Overcurrent/short‑circuit protection
- Undervoltage and overvoltage lockout
- Thermal shutdown
- Fault/status indication (FLT/STAT) and an enable (EN) input
Typical uses:
- Hot‑swap protection in servers, telecom, industrial, and consumer power rails
- Safe power‑up/down for downstream ICs and modules
Packaging: DBV package (RoHS compliant). For exact electrical specs, pinout, recommended circuits, and part options, see the TI TPS2514A product page and datasheet.

TPS2514ADBVR features (highlights):
- 1-channel hot-swap controller requiring an external N-channel MOSFET for high-side switching.
- Programmable current limit via an external sense resistor (ILIM).
- Slew-rate limited startup (soft-start) to minimize inrush.
- Input undervoltage lockout (UVLO) for reliable enable/disable.
- Overvoltage protection (OVP) on the input.
- Overcurrent protection with fast protection and optional latch/auto-retry behavior.
- Thermal protection to shield MOSFET/load at high temperature.
- Fault/Status signaling (FLT/open-drain) for system reporting and control.
- Small 8-pin package (DBVR variant), suitable for backplane/telecom or hot-swap environments.
Note: It is a single-channel hot-swap controller that uses an external MOSFET; no internal power FET is included.

- Pin count: 20 pins (DBV package, VSSOP-20)
- Function: Quad high-side load switch for power distribution with current limit and protections. Four independent channels with enable/control, soft-start, reverse-current blocking, and fault/status reporting (UVLO/OC/thermal protection).

Manufacturer: Texas Instruments (TI).
Company type: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits for a wide range of industries.

TPS2514ADBVR is a dual-channel hot-swap controller for two power rails. It drives external MOSFETs to limit inrush, provides per-channel current limit and overcurrent/short-circuit protection, and offers fault/status signaling.
Typical applications:
- Hot-swap backplanes for servers, storage arrays, and telecom/network gear
- Dual-rail power distribution on motherboards, PCIe/SAS backplanes, and plug-in modules
- Industrial equipment requiring controlled startup and protection of two rails
It helps prevent damage during insertion/removal and reduces supply noise during power-up.

TPS2514ADBVR uses a VSSOP-8 package (package code DBV); Tape-and-Reel (R) version.
