The TrenchFET technology provides ultra-low 62mOhm RDS(on) at VGS=4.5V in a tiny SOT-23 package. The logic-level gate threshold (0.65V min) enables direct drive from 2.5V\/3.3V logic. The low 5.4nC gate charge supports high-frequency switching. This device is one of the most popular small-signal MOSFETs for load switching and power management in portable electronics.","working_principle":"The SI2302CDS-T1-GE3 operates as a logic-level N-channel TrenchFET MOSFET. (1) The TrenchFET cell structure uses vertical trenches in the silicon to create the gate electrode, providing much higher channel density than planar MOSFETs. This results in the ultra-low 62mOhm RDS(on) at VGS=4.5V despite the tiny SOT-23-3 package. (2) The logic-level gate threshold of 0.65V minimum allows the MOSFET to be driven directly from 2.5V or 3.3V GPIO without a gate driver. At VGS=2.5V, the RDS(on) is still only 95mOhm max, providing efficient switching for battery-powered loads. (3) The 5.4nC total gate charge enables switching frequencies up to several hundred kHz with minimal gate drive loss. The 2.2A continuous drain current rating covers most portable electronics load requirements. The 20V VDS is compatible with single-cell Li-ion battery systems and 5V USB power.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>GATE<\/td><td>MOSFET gate drive output; connect to gate of external N-channel MOSFET through series resistor (1-10 Ohm)<\/td><\/tr><tr><td>2<\/td><td>SOURCE<\/td><td>MOSFET source connection; connect to MOSFET source and current sense resistor<\/td><\/tr><tr><td>3<\/td><td>DRAIN<\/td><td>MOSFET drain voltage sense; monitors forward voltage drop across MOSFET for regulation<\/td><\/tr><\/table><p>Package: SOT-23-3 (MicroPak).
