产品描述

The GLF4033 is an integrated power multiplexer IC featuring dual independent power switches connected to a single output, enabling seamless transitions between two input power sources. The device supports a manual selection mode, configurable via the logic input pins S1 and S2. These pins allow system designers to manually select VIN1 only or VIN2 or and disable both switches.

The GLF4033 features low conduction resistance, enabling robust 4 A continuous current handling capability per channel. The device incorporates advanced cross-conduction protection that actively prevents current flow between input sources, maintaining isolation regardless of which power supply is active. The GLF4033 is ideally suited for power systems requiring an internal backup power supply.
