Product details

Active high-side switch in a rework-friendly SOT-23-6

The MIC2019A-2YM6-TR: The non-inverting input and P-channel output configuration simplify drive logic — a logic high on the On/Off control pin turns the switch on without requiring an external Vcc supply, as the device is self-powered from the load rail.

The 170 mOhm typical Rds(on) at 5 V gate drive translates to about 140 mV drop at 900 mA and roughly 130 mW of conduction loss — manageable in the SOT-23-6 package if the PCB copper is adequate, but at the upper end of the thermal budget at 85°C ambient without airflow.

SOT-23-6 — hand-reworkable, but watch the pad

Pin 1 orientation is marked by a dot on the top of the package; verify the footprint matches the supplier device package drawing before layout.
