LTC4226IMS-1#TRPBF

Hot Swap Controllers Overview

The LTC4226IMS-1#TRPBF is a dual hot swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of live circuit boards. It operates within a supply voltage range of 4.5 V to 44 V and supports external N-channel MOSFETs. The device features programmable current limiting, fault timeout, and overvoltage protection with latch-off capability. It consumes 700 µA of supply current and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a 16-pin MSOP (TFSOP) surface-mount package.

Hot Swap Controllers Feature Summary

• Dual channel architecture supporting independent control of two high-voltage hot swap paths
• Programmable circuit breaker with adjustable current limit and fault timeout settings
• Latch-off fault management mode that requires explicit reset after error events
• Integrated undervoltage lockout ensuring stable operation during power ramp-up

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe board insertion
• Industrial control systems with modular I/O cards
• Data center infrastructure managing hot-pluggable server blades
• Test and measurement instruments needing protected power rails

Hot Swap Controllers Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the IMS-1 designation corresponds to the specific latch-off variant and commercial temperature grade. Ensure compatibility with external N-channel MOSFET gate drive requirements. Check for RoHS compliance documentation from Analog Devices. Validate pinout alignment with target PCB footprint before procurement.

Hot Swap Controllers Selection Notes

Select this component for applications requiring dual-channel hot swap protection with latch-off fault handling. Suitable for systems operating between 4.5 V and 44 V where external FETs are preferred for higher current capacity. Consider the 700 µA quiescent current for low-power standby modes. Verify that the 16-pin MSOP package fits the available board space. Ensure the design accommodates external sense resistors for current programming.

Hot Swap Controllers Part Context

This part belongs to the LTC4226 family of hot swap controllers from Analog Devices. It shares functional similarities with other devices in the series but differs in package type and fault response configuration. The IMS-1 variant specifically offers latch-off behavior, distinguishing it from auto-retry versions. It complements other PMIC solutions in complex power distribution networks.

Hot Swap Controllers Replacement Considerations

LTC4226IMS-1#PBF is the tube-packaged equivalent of this reel-delivered part. Both share identical electrical characteristics and functionality. Substitution depends solely on packaging preference and manufacturing line requirements. No functional changes occur between these variants.
