MAX16551 Overview
The MAX16550/MAX16551 are protection ICs with an integrated low-resistance MOSFET and lossless currentsense circuitry featuring SMBus/PMBus™ control and reporting. The ICs are 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.
