500 mA high-side switch with load discharge — portable rail control
The BD2200GUL-E2: The BD2200GUL- is a single-channel high-side load switch from ROHM, built in an N-channel MOSFET configuration. The load discharge feature pulls the output to ground when the switch is off, preventing a floating output that could hold up a downstream load. The input type is non-inverting and the interface is a simple On/Off logic pin, so it integrates directly with a GPIO from an MCU or system controller without external level shifting. No Vcc supply is needed for the switch itself — the gate drive is derived from the load voltage, keeping the BOM count low.
Package and board-fit — VCSP50L1 footprint
This is a wafer-level chip-scale package — the die is essentially the package, so the footprint matches the silicon size. Operating temperature range is -25°C to 85°C, covering consumer portable gear and most indoor industrial environments.
