What are the key features of LTC4222IUH#PBF?
- Dual-channel hot-swap control with adjustable current limit and inrush management on 2.9 V to 15 V supply rails
- Integrated 12-bit ADC with I2C interface for real-time monitoring of current, voltage, and power per channel
- Adjustable overcurrent and undervoltage thresholds in a compact 32-lead QFN package enabling high-density power management
What is LTC4222IUH#PBF used for?
LTC4222IUH#PBF is deployed in blade server and ATCA/AdvancedTCA chassis where live-insertion of boards requires controlled inrush current on dual 12 V or 3.3 V supply rails to prevent rail droop. Its I2C telemetry port streams real-time current and power readings to a system management controller for predictive thermal and load management. The device is also used in telecom line cards and industrial hot-plug backplanes where continuous power monitoring across 2 channels is required alongside autonomous fault protection.

Frequently Asked Questions
What supply voltage range does LTC4222IUH#PBF support for hot-swap control?
LTC4222IUH#PBF operates across a supply voltage range of 2.9 V to 15 V per channel, covering common bus voltages including 3.3 V, 5 V, and 12 V. This wide range lets a single device manage dual mixed-voltage rails in server backplanes or distributed power architectures without external level-shifting circuitry.
How does the integrated 12-bit ADC on LTC4222IUH#PBF benefit a server power management design?
The onboard 12-bit ADC samples current-sense, voltage, and calculated power for both channels and presents the results over I2C, eliminating the need for a separate external ADC. With 12-bit resolution, the system can detect supply current changes as small as a few milliamps, enabling early fault detection and precise per-slot power budgeting in multi-board chassis.
When is LTC4222IUH#PBF a better choice than a discrete MOSFET plus comparator for hot-swap protection?
LTC4222IUH#PBF integrates adjustable current limiting, a 12-bit ADC, and I2C telemetry in a single 32-lead QFN, replacing at minimum 6–10 discrete components. This integration reduces BOM count, shrinks PCB area by roughly 60–70%, and provides accurate digital readback that a comparator-based discrete circuit cannot offer, making it preferable whenever real-time power monitoring alongside protection is required.
What package does LTC4222IUH#PBF use and how does it affect PCB thermal design?
LTC4222IUH#PBF is housed in a 32-lead 5 mm × 5 mm QFN package with an exposed pad on the underside. The exposed pad must be soldered to a PCB copper pour connected to at least 4 thermal vias to achieve the required junction-to-board thermal resistance of approximately 20°C/W, ensuring the IC stays within its -40°C to +85°C industrial operating temperature range under full load.
