The Analog Devices LTC4357CDCB#PBF with Power Management Specialized is an ultra-low quiescent current high voltage ideal diode controller designed to reduce power dissipation in automotive, telecom/datacom, and industrial applications. It combines a high-speed voltage comparator, a 1.2O N-channel MOSFET switch, and an external current-sense resistor to provide accurate current limiting and maximum power transfer efficiency at the diode switch node.The LTC4357CDCB#PBF has an operating temperature range of -40°C to 125°C, a minimum operating voltage of 3V, and a maximum operating voltage of 55V. With its low quiescent current (220µA) and switch resistance of 1.2O, this device is able to achieve very high efficiency for ultra-low power applications. The LTC4357CDCB#PBF also features overvoltage protection, reverse current protection, and fault reporting capability.
