MAX16545BGPF+T from Analog Devices / Maxim Integrated is a circuit-breaker and hot-swap protection IC for 12 V distribution, integrating a low-resistance power MOSFET, lossless current sensing, and PMBus/SMBus telemetry.
Specifications were checked against the manufacturer Rev. 6 data sheet and current product page; price tiers were checked on the exact DigiKey order-code listing.
The MAX16545B combines power switching, current measurement, protection, and digital reporting in a compact 6.5 mm x 4 mm package. Its integrated 0.95 mOhm power path supports high-current 12 V distribution, while programmable soft start, three overcurrent levels, voltage monitoring, and rapid isolation protect servers and communications equipment.
Integrated MOSFET and package provide a 0.95 mOhm total 12 V power path for up to 60 A designs.
Precise integrated current sensing reports load current without an external shunt.
PMBus/SMBus supports configuration, control, telemetry, status, and fault reporting.
Severe overcurrent isolation is below 5 us and fail-safe isolation is below 250 ns.
12 V circuit breaker, hot swap, inrush control, and rail monitoring
MAX16545B is configured for a 16 A startup overcurrent threshold
ILOAD provides an accurate signal proportional to load current
22-FCQFN (4 mm x 6.5 mm) / 22-VFQFN
The exact order code is identified by Analog Devices as LFCSP and by DigiKey as a 22-VFQFN package with 22-FCQFN (4 mm x 6.5 mm) supplier designation. This +T order code is supplied in tape-and-reel packaging.

MAX16545BGPF+ is the verified internal tray-packaged counterpart. Electrical function is shared, but packing, assembly process, lot handling, and procurement requirements must be confirmed.
Analog Devices lists MAX16545BGPF+T as a production order code. This summary uses the current MAX16545B product page and the MAX16545B/MAX16545C Rev. 6 data sheet.
Distributes and protects high-current 12 V rails with telemetry and rapid fault isolation.
Adds managed hot-swap, inrush control, rail monitoring, and circuit-breaker protection.
Provides a digitally monitored protected output path for dense power systems.
Match the complete order code, reel label, package marking, lot traceability, and moisture handling records to authorized-channel documentation before high-current production use.
Yes. It integrates the power MOSFET and lossless current sensing in the protection IC package.
PMBus/SMBus provides telemetry and status, while ILOAD supplies an analog current indication.
This +T version is tape-and-reel; the linked + version is the tray-packaged order code.
No. The registered local JPG is missing, so publication is blocked.
Use the latest manufacturer data sheet for thresholds, PMBus programming, high-current copper, thermal analysis, fault response, and production approval. Distributor data supports sourcing but does not replace manufacturer limits.
