Product Overview

The LTC4352CMS#PBF is a low voltage Ideal Diode Controller with monitoring. It creates a near-ideal diode using an external N-channel MOSFET. It replaces a high power Schottky diode and the associated heat sink, saving power and board area. The ideal diode function permits low loss power ORing and supply holdup applications. The LTC4352 regulates the forward voltage drop across the MOSFET to ensure smooth current transfer in diode-OR applications. A fast turn-on reduces the load voltage droop during supply switch-over. If the input supply fails or is shorted, a fast turn-off minimizes reverse currents. The controller operates with supplies from 2.9 to 18V. For lower voltages, an external supply is needed at the VCC pin. Power passage is disabled during under voltage or overvoltage conditions. The controller also features an open MOSFET detect circuit that flags excessive voltage-drop across the pass transistor in the on state.
