Frequently Asked Questions
What on-resistance and drain current rating does IRLML2244TRPBF offer for load switching applications?
The IRLML2244TRPBF P-Channel MOSFET delivers a maximum on-resistance (RDS(on)) of 54 mΩ at a drain current up to 4.3 A, with a 20 V drain-source breakdown voltage. This low 54 mΩ on-resistance minimizes I2R conduction losses in load switch circuits, making it efficient for battery-powered devices operating from 3 V to 20 V supply rails.
Which battery management circuit topologies benefit from using IRLML2244TRPBF as a high-side switch?
Li-ion and Li-Po single-cell battery protection circuits, USB power switching, and reverse polarity protection designs benefit from IRLML2244TRPBF as a high-side P-Channel switch. The 20 V maximum VDS and 4.3 A drain current handling allow it to manage charging and discharging paths in 1S battery packs at currents up to 4 A, while its 54 mΩ on-resistance ensures minimal voltage drop during peak load conditions.
How does IRLML2244TRPBF in SOT-23 compare to larger package alternatives for board space in IoT designs?
In IoT module PCB designs, the IRLML2244TRPBF SOT-23 (TO-236AB) 3-pin package occupies approximately 2.9 mm x 1.3 mm of board space, significantly smaller than D-PAK or TO-252 P-Channel MOSFETs that may use 6 mm x 6 mm or larger footprints. For IoT sensor nodes and wearable devices switching loads up to 4.3 A at 20 V, the SOT-23 form factor delivers equivalent switching capability in a fraction of the PCB area.
