500 mA high-side switch with integrated protection
The MIC2015-0.5YM6-TR is a single-channel, high-side power switch from Microchip Technology, delivering up to 500 mA continuous output from a P-channel MOSFET with a typical on-resistance of 70 mOhm. The non-inverting input logic enables direct connection to a GPIO or enable signal, with the output following the input state at a 1:1 ratio.
Slew-rate control and fault protection for downstream loads
Slew-rate controlled switching limits the output voltage rise time, reducing inrush current into capacitive loads and minimizing supply rail droop during turn-on — relevant when the load side has decoupling capacitors or a downstream regulator input. Built-in fault protection includes fixed current limiting and over-temperature shutdown, which together guard the switch and the load against short-circuit events and thermal runaway. The 70 mOhm typical Rds(on) at 500 mA produces roughly 17.5 mW of conduction loss at full load — negligible in most layouts, but the SOT-23-6 package's thermal impedance to ambient should be considered if the switch operates near the 85°C upper limit continuously.
Package and board-fit: SOT-23-6
Housed in a 6-lead SOT-23 package (supplier device package SOT-23-6), the part is intended for surface-mount assembly on standard FR-4 with a 0.95 mm pitch footprint.
