Key Features
- 4-channel high-current hot swap control with adjustable overcurrent and overvoltage thresholds for flexible system protection
- I2C-compatible digital monitoring interface enables real-time fault status, voltage, and current readback in server and telecom power architectures
- 32-lead QFN (S-PQCC-N32) package minimizes PCB footprint while delivering robust hot swap management for high-density power distribution boards
Applications
The LTC4282CUH#TRPBF is used in high-availability server, telecom, and data center power distribution systems where live board insertion and removal must be performed without disrupting system operation. Its 4 channels and I2C monitoring bus allow centralized power management controllers to read back voltage, current, and fault states from multiple hot swap rails simultaneously. Adjustable threshold settings make it adaptable to 3.3 V, 5 V, 12 V, and 48 V distribution architectures commonly found in ATCA, bladed server chassis, and industrial computing platforms.

Frequently Asked Questions
How many hot swap channels does the LTC4282CUH#TRPBF control and what interface is used for monitoring?
The LTC4282CUH#TRPBF controls 4 independent hot swap channels with adjustable overcurrent and overvoltage thresholds. It includes an I2C-compatible serial monitoring interface that allows a system management controller to read real-time voltage, current, and fault status from all 4 channels over a 2-wire bus at standard I2C speeds.
Which supply voltage rails is the LTC4282CUH#TRPBF designed to protect in live-insertion systems?
The LTC4282CUH#TRPBF supports adjustable threshold settings that make it compatible with multiple supply rails including 3.3 V, 5 V, 12 V, and 48 V commonly found in ATCA and bladed server chassis. The adjustable overcurrent limit allows designers to tailor protection for each rail's maximum load current, preventing damage during hot swap insertion transients.
What package does the LTC4282CUH#TRPBF use and what are its key physical characteristics?
The LTC4282CUH#TRPBF is housed in a 32-lead QFN (Quad Flat No-Lead, S-PQCC-N32) plastic package with an exposed thermal pad for improved heat dissipation. The compact QFN footprint enables dense placement on power management PCBs in 1U server boards, line cards, and high-current power distribution modules where board space is constrained.
When would a designer choose the LTC4282 over a simpler single-channel hot swap controller?
A designer selects the 4-channel LTC4282CUH#TRPBF over single-channel alternatives when a system has multiple independent power rails — such as 3.3 V, 5 V, 12 V, and an auxiliary rail — that all require hot swap protection and I2C monitoring. Centralizing 4 channels in one IC reduces component count, simplifies the PCB layout, and provides a single I2C node for monitoring all rails simultaneously in high-availability server or telecom chassis.
