AOZ1377DI-01

Power Distribution Switches, Load Drivers Overview

The AOZ1377DI-01 is a USB Type-C protection switch manufactured by Alpha & Omega Semiconductor. It integrates N-channel MOSFETs to function as both a sink and source switch with a 20V input rating and 7A current capability. The device features a low on-state resistance of 19mΩ, reducing voltage drop and power loss compared to back-to-back p-channel alternatives. It includes True Reverse Current Blocking (TRCB) to prevent undesired reverse current flow from VOUT to VIN. Packaged in a compact 10-DFN (3x3mm) surface-mount format, it supports structural integrity for portable applications.
