Product Details
MAX16545BGPF+ - 60 A Integrated 12 V Bus Protection IC
MAX16545BGPF+ 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.
Overview
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.
Key Advantages
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.
Feature Summary
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
Package & Footprint
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 non-T order code is supplied in trays.

Replacement Considerations
MAX16545BGPF+T is the verified internal tape-and-reel counterpart. Electrical function is shared, but packing, assembly process, lot handling, and procurement requirements must be confirmed.
Manufacturer Information
Analog Devices lists MAX16545BGPF+ as a production order code. This summary uses the current MAX16545B product page and the MAX16545B/MAX16545C Rev. 6 data sheet.
Applications
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.
Quality & Authenticity
Match the complete order code, tray label, package marking, lot traceability, and moisture handling records to authorized-channel documentation before high-current production use.
FAQ
Does MAX16545B include the power MOSFET?
Yes. It integrates the power MOSFET and lossless current sensing in the protection IC package.
How is the device monitored?
PMBus/SMBus provides telemetry and status, while ILOAD supplies an analog current indication.
What differs from MAX16545BGPF+T?
The +T version is tape-and-reel; this + version is the tray-packaged order code.
Is the package image ready?
No. The registered local JPG is missing, so publication is blocked.
Engineering Notice
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.
