What are the key features of LTC4226IUD-2#TRPBF?
- Dual-channel hot-swap control from 4.5 V to 44 V wide input range with independent MOSFET gate drive for two supply rails
- Auto-retry on fault with adjustable current threshold allows hands-free power recovery without processor intervention
- Compact 16-lead QFN (4 mm x 4 mm) package enables high board density in server, telecom, and industrial hot-plug applications
What is LTC4226IUD-2#TRPBF used for?
The LTC4226IUD-2 is used in server blades, ATCA and cPCI carrier cards, and telecom line cards where two supply rails must be safely hot-inserted into a live backplane without voltage glitches or inrush current damage. Its 4.5 V to 44 V operating range and auto-retry make it equally effective in industrial 24 V and 48 V distributed power architectures.

Frequently Asked Questions
What voltage range does the LTC4226IUD-2 support for hot-swap control?
The LTC4226IUD-2 operates across a 4.5 V to 44 V input range, covering both 5 V and 48 V telecom bus voltages. It drives external N-channel MOSFETs on 2 independent channels, and the adjustable overcurrent threshold lets designers set trip levels precisely for each rail's load current.
How does the auto-retry feature of the LTC4226IUD-2 simplify system-level fault management?
After an overcurrent or short-circuit event, the auto-retry mode automatically re-enables the MOSFET gate after a programmable timeout, typically set by an external capacitor, without requiring a microcontroller command. This reduces firmware complexity in 48 V server and ATCA systems where thousands of hot-swap slots must recover autonomously within milliseconds.
Which package does the LTC4226IUD-2#TRPBF use, and how does it affect PCB layout?
The device comes in a 16-lead QFN (4 mm x 4 mm) plastic package with an exposed thermal pad, giving a very small PCB footprint suitable for high-density blade designs. Gate-drive routing to external MOSFETs should be kept under 25 mm to minimize inductance, and the exposed pad should be soldered to the ground plane for thermal relief.
