No external Vcc supply is required — the gate drive is derived from the load voltage, which simplifies the BOM for a single-rail system. ## Package and board integration The MAX891LEUA+ is offered in an 8-uMAX/uSOP (3.00 mm width) surface-mount package, supplied in tube format. The narrow 0.118-inch pitch lands on a standard MSOP-8 footprint.","metaTitle":"MAX891LEUA+ Analog Devices Power Switch, 500 mA, 8-uMAX","metaDescription":"MAX891LEUA+ high-side P-channel power switch, 500 mA, 2.7-5.5 V load, 120 mOhm Rds on, active production, ROHS3.
