Microchip Technology, Inc. PMIC - PMIC - Power Distribution Switches, Load Drivers - MIC2027-1YM MIC2027-1YM

The MIC2027/2077 is a quad high-side MOSFET power distribution switch designed for general-purpose applications requiring circuit protection. It operates within a voltage range of 2.7V to 5.5V and supports a minimum continuous current of 500mA per channel. The device features a maximum on-resistance of 150m,Ѷ per channel, ensuring efficient power management. Key protective features include short-circuit protection with thermal shutdown, undervoltage lockout, and reverse current flow blocking, which eliminates the risk of damage from body diode conduction. The MIC2077 variant includes a circuit breaker mode that reduces power consumption during fault conditions. Both devices are equipped with a fault status flag that indicates overcurrent or thermal shutdown conditions, and they incorporate soft-start circuitry to minimize inrush current. The MIC2027/2077 is available in 16-pin narrow and wide SOIC packages, making it suitable for various applications, including USB peripherals, notebook PCs, and ACPI power distribution. The operating temperature range is from -40¬8C to +85¬8C, ensuring reliability in diverse environments.
