LTC2928IUHF#TRPBF

LTC2928IUHF#TRPBF is an I2C-controlled hot-swap/load-switch controller from Linear Technology ( Analog Devices). It drives a high-side MOSFET, monitors load current with an external sense resistor, and provides programmable current limit and soft-start to protect power rails during insertion/removal.
Key features (typical):
- I2C interface for programming current limit, delays, and fault handling
- Integrated current limit, overcurrent protection, and short-circuit protection
- Overvoltage/undervoltage detection and fault reporting with latches or status outputs
- Soft-start sequencing and programmable fault response
- Fault flag/interrupt outputs for host controller
Suffix notes:
- #TRPBF indicates tape-and-reel packaging, Pb-free (RoHS-compliant)
- IUHF denotes the specific package/temperature variant of the part (check the datasheet for exact packaging and temp range)
Typical uses:
- Safe insertion/removal of boards and modules
- Power rail protection in servers, telecom equipment, and network/storage appliances
For exact electrical specs, pinout, and packaging details, consult the LTC2928 datasheet and the packaging table.

- Pin count: 16 pins (LTC2928IUHF in the UHF package).
- Function: Single-rail hot‑swap controller with programmable current limit and soft‑start, providing protection (overcurrent/overvoltage/UVLO) and status/flag outputs; used to protect and monitor a power rail, typically with a control interface for status.

Analog Devices, Inc. (ADI) is the manufacturer. It is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and signal-processing integrated circuits. The LTC prefix originates from Linear Technology, which was acquired by Analog Devices in 2017.

Applications of LTC2928IUHF#TRPBF:
- Hot‑swap protection with inrush control for backplanes and daughter cards
- DC rail protection and monitoring (12–48V) in automotive, industrial, telecom, and data‑center equipment
- I2C-controlled current limit, fault reporting, and power sequencing
- General DC power‑management in embedded/industrial systems requiring safe insertion/removal and fault handling
