The MIC2090-2YM5-TR is a 50mA current-limiting high-side power distribution switch manufactured by Microchip Technology, featuring latch-off overcurrent protection in a compact SOT-23-5 package. Part of the MIC2090\/2091 family, this P-channel MOSFET switch is optimized for general-purpose low-power distribution in circuits requiring over-current limiting and circuit protection, with an input voltage range of 1.8V to 5.5V and a typical RDS(ON) of 700mOhm.<\/p>\n

Built around a P-channel MOSFET with a typical RDS(ON) of 700mOhm at 3.3V, the device operates from a 1.8V to 5.5V supply and features reverse current blocking, thermal shutdown, undervoltage lockout, and an open-drain fault flag. The latch-off version (-2 suffix) ensures the output remains off after an overcurrent event until the enable pin is toggled, providing robust protection for sensitive downstream circuits. The SOT-23-5 package minimizes board space while the -40\u00b0C to +125\u00b0C junction temperature range supports demanding environments.","working_principle":"The MIC2090-2YM5-TR integrates a P-channel MOSFET as the switching element between VIN and VOUT, controlled by an active-high enable (EN) pin. When enabled, the MOSFET conducts and delivers power to the load. The current-limiting circuitry monitors output current; when it exceeds the 50mA threshold, the latch-off mechanism turns off the MOSFET and asserts the FAULT flag low. The device remains latched off until EN is toggled low then high. Reverse current blocking prevents current flow from VOUT to VIN when the switch is off. UVLO ensures the switch remains off when VIN is below 1.75V, while thermal shutdown protects against excessive junction temperature.","pin_description":"\n
