# IRLML2502 Application and Usage Guide
The IRLML2502 is an Infineon / International Rectifier logic-level N-channel enhancement-mode power MOSFET in a three-lead Micro3 SOT-23 package, intended for compact battery and load-management switching applications ([manufacturer datasheet](https://www.infineon.com/dgdl/irlml2502pbf.pdf?fileId=5546d462533600a401535668048e2606)). Its most straightforward schematic use is a microcontroller-controlled low-side load switch, with the source grounded, the drain connected to the load return, and a defined gate-to-source pull-down.
