MAX16550GPN+ by Analog Devices

Integrated Protection IC on 12V Bus with an Integrated MOSFET, Lossless Current Sensing, and PMBus Interface


The MAX16550 is a protection IC with an integrated low-resistance MOSFET and lossless currentsense circuitry featuring SMBus/PMBus™ control and reporting. This IC is designed to provide the optimum solution for distribution, control, monitoring and protection of the system’s 12V power supply. An internal LDO provides the supply voltage for the protection IC. If no fault is detected, the IC initiates the startup and has been designed to provide controlled, monotonic startup. Programmable soft-start ramp and delay is implemented to limit the in-rush current during startup. The IC monitors the current and voltage of the 12V system power rail and provides multiple levels of protection with fast turn-off if a fault is detected. Maxim’s patented, lossless current sense provides high accuracy current sensing over load and temperature, improving overall system-energy efficiency, and reducing dissipation. Output voltage is monitored at all times. If at any time the output voltage falls below the programmable output undervoltage-lockout threshold, the PWRGD signal is asserted low. If at any time the input voltage falls below the programmable input undervoltage-lockout threshold, the PWRGD signal is asserted low. The IC can be programmed through PMBus to provide input overvoltage protection. Input overvoltage protection is disabled by default. When enabled through PMBus, if the input voltage exceeds a programmable overvoltage threshold, the MOSFET is latched off and a fault indicated.
