Microchip Technology, Inc. PMIC - PMIC - Power Distribution Switches, Load Drivers - MIC2039BYMT-TR MIC2039BYMT-TR

The MIC2039BYMT-TR is a high-side MOSFET power distribution switch designed for applications requiring adjustable current limits. It operates within an input voltage range of 2.5V to 5.5V and features a low quiescent current of 100 ¬µA when the switch is on. The device offers a current-limit accuracy of ¬±5% and allows for adjustable output current from 0.2A to 2.5A, which can be set using external resistors. Key features include a kickstart function that permits momentary high-current surges, a soft-start capability, and an undervoltage lockout (UVLO) to enhance system reliability. The MIC2039 also includes thermal shutdown protection and a fault status output flag that indicates overcurrent or thermal shutdown conditions. It is available in both 6-pin SOT-23 and 6-pin 2mm x 2mm thin DFN packages, with a junction temperature range from -40¬8C to +125¬8C, making it suitable for various applications such as USB peripherals, consumer electronics, and general-purpose power distribution.
