BD2227G-LBTR

Power Distribution Switches, Load Drivers Overview

The BD2227G-LBTR is a single-channel high-side switch IC designed for USB and memory card power distribution. It integrates a low on-resistance N-channel MOSFET with comprehensive protection features including overcurrent detection, thermal shutdown, under-voltage lockout, and soft-start functionality. The device operates within a supply voltage range of 2.7V to 5.5V and supports an active-low control input logic. It provides continuous load current capability up to 0.75A and includes a recovery flag output pin to indicate fault conditions. The component is housed in a compact SSOP-5 package suitable for space-constrained applications.
