UM3865P Load Switch with Level-Shift UM3865P SOT363 General Description The UM3865P includes a p- and n-channel MOSFET in a single SOT363 package. The low on-resistance p-channel MOSFET is tailored for use as a load switch. The n-channel, with an external resistor, can be used as a level-shift to drive the p-channel load switch. The n-channel MOSFET has internal ESD protection and can be driven by logic signals as low as 1.5V. The UM3865P operates on supply lines from 1.8V to 8V, and can drive loads up to 1A.
