MIC2090/MIC2091 July 2011 2 M9999-070611-B Ordering Information Part Number Marking Current Limit Current-Limit Recovery Junction Temperature Range Package MIC2090-1YM5 L1K 50mA Auto-Retry –40 °C to +125°C SOT-23-5 MIC2091-1YM5 M1K 100mA Auto-Retry –40 °C to +125°C SOT-23-5 MIC2090-2YM5 L2K 50mA Latch-Off –40 °C to +125°C SOT-23-5 MIC2091-2YM5 M2K 100mA Latch-Off –40 °C to +125°C SOT-23-5 Pin Configuration 5-Pin SOT-23 (M5) Pin Description Pin Number Pin Name Pin Function 1 VIN Supply (Input): +1.8V to +5.5V. Provides power to the output switch and the MIC2090/MIC2091 internal control circuitry. 2 GND Ground. 3 EN Enable (Input): Active-high TTL compatible control input. A high signal turns on the internal switch and supplies power to the load. This pin cannot be left floating. 4 FAULT/ Fault Status (Output): Open drain output. Can be connected to other open drain outputs. Must be pulled high with an external resistor. When EN=0, FAULT/ pin is high When EN=1, a low on the FAULT/ pin indicates one or more of the following conditions: 1. The part is in current limit and is turned off. 2. The part is in thermal limit and is turned off. 3. The part is in UVLO 5 VOUT Switched Output (Output): The voltage on this pin is controlled by the internal switch. Connect the load driven by the MIC2090/MIC2091 to this pin. |
