AP2145MPG-13

Overview

The AP2145MPG-13 is a high-side power distribution switch manufactured by Diodes Incorporated. It features a single output channel with a maximum continuous output current of 500 mA and an internal on-resistance (RDS(on)) of 140 mOhms. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes active-low enable control. Integrated protection mechanisms include overcurrent limiting, thermal shutdown, and undervoltage lockout. It is housed in an MSOP-8 EP package and supports surface-mount installation across an operating temperature range of -40°C to +85°C.
