Key Features
- Quad-channel hot-swap controller managing 4 independent load switches from a single IC
- 2.9 V to 15 V input range with 12 V nominal operation for standard server board rails
- Programmable overcurrent limiting and fault detection for each channel independently
- 38-pin XMA package enabling dense board layout in rack-mounted server and telecom equipment
- REACH-compliant construction supporting green electronics design requirements
Applications
The LTC4234CWHH#PBF is targeted at high-availability server boards, telecom line cards, and storage arrays that require safe hot-plug insertion of multiple supply rails simultaneously. Its quad-channel architecture allows one IC to protect four separate 12 V power paths, reducing the component count compared to using four discrete hot-swap controllers. Data center power distribution units and industrial rack systems benefit from its programmable current limits and per-channel fault isolation for improved system uptime.

Frequently Asked Questions
How many channels does LTC4234CWHH#PBF control, and over what input voltage range?
The LTC4234CWHH#PBF manages 4 independent hot-swap load switch channels and operates over an input voltage range of 2.9 V to 15 V, with 12 V as the nominal rail, covering the most common server and telecom board supply levels in a single IC.
How does LTC4234CWHH#PBF protect against overcurrent during hot-plug events in server boards?
Each of its 4 channels includes programmable overcurrent limiting set by an external sense resistor, allowing inrush current to be capped to a safe level during board insertion, with per-channel fault flags that isolate a failed channel without disrupting the remaining 3 active channels.
In which high-density applications does the 38-pin XMA package of LTC4234CWHH#PBF offer a layout advantage?
The 38-pin XMA package combines 4-channel hot-swap control into a footprint suitable for high-density rack server blades and telecom line cards where PCB space is at a premium, replacing up to 4 separate single-channel controllers and reducing board area by approximately 60%.
When comparing LTC4234CWHH#PBF to a single-channel hot-swap IC for a 4-rail server design, what is the BOM impact?
Using LTC4234CWHH#PBF replaces 4 single-channel hot-swap controllers with 1 device, reducing the IC count by 3 parts, lowering passive component count proportionally, and simplifying firmware since all 4 channels share a single I2C or control interface at a 2.9 V to 15 V input range.
