MAX16545B/MAX16545C Circuit-Breaker Protection IC
Analog Devices Inc. MAX16545B/MAX16545C Circuit-Breaker Protection IC has an integrated low-resistance MOSFET and lossless current-sense circuitry featuring PMBus™/SMBus control and reporting. The IC is designed to provide the optimum solution for distributing, controlling, monitoring, and protecting the system’s 12V power supply. An internal LDO provides the bias supply voltage for the protection IC. If no fault is detected, the MAX16545B/MAX16545C initiates the startup. The device has been designed to provide a controlled, monotonic startup. Programmable soft-start ramp and delay are implemented to limit the inrush current during startup. The MAX16545B is set for 16A Startup OCP, and the MAX16545C is set for 24A Startup OCP.
