MAX16545BGPF+T

Specialized ICS Overview

The MAX16545BGPF+T is a circuit-breaker protection IC designed for 12V power distribution systems. It integrates a low-resistance N-channel MOSFET with an on-resistance of 0.95mΩ and lossless current-sense circuitry. The device features PMBus/SMBus control, programmable soft-start, and three levels of overcurrent protection: moderate, severe, and safe shutdown. An internal LDO provides the bias supply voltage. The component operates within a junction temperature range of 0°C to +125°C and is housed in a 22-FCQFN package.

• Integrated 0.95mΩ Power MOSFET with Lossless Current Sensing
• PMBus/SMBus Interface for Telemetry and Control
• Three-Level Overcurrent Protection (Moderate, Severe, Safe)
• Internal 1.8V LDO Bias Supply

Specialized ICS Applications

• Servers
• Networking Equipment
• Storage Systems
• Communication Equipment
• AC/DC Power Supplies

Specialized ICS Procurement Notes

Verify the specific suffix 'GPF' against official manufacturer documentation to confirm package details and RoHS compliance status. Ensure the ordering code matches the exact tape-and-reel or cut-tape configuration required for the production line. Cross-reference the datasheet revision date to confirm parameter accuracy.

Specialized ICS Selection Notes

Select the MAX16545B variant for a default startup overcurrent protection threshold of 16A. Select the MAX16545C variant for a default startup threshold of 24A. Both variants support programmable thresholds via PMBus. Ensure the application requires a 12V bus architecture compatible with the specified input voltage range of 10.8V to 13.2V.

Specialized ICS Part Context

This component belongs to the MAX16545 family of integrated protection ICs manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants differentiated primarily by their factory-set startup overcurrent protection limits. These devices are engineered to replace conventional discrete circuit breaker solutions in high-density power distribution designs.
