Microchip Technology, Inc. PMIC - Power Distribution Switches, Load Drivers MIC2033-05BYM6-TR

The MIC2033-05BYM6-TR is a high-side power distribution switch designed for applications requiring reliable current limiting and thermal protection. It operates within an input supply range of 2.5V to 5.5V and features a low quiescent current of 100 ¬µA when the switch is on. The device offers fixed current-limit options of 0.5A, 0.8A, 1A, and 1.2A, with a typical R_DS(ON) of 75 m,Ѷ at 5V, ensuring efficient power management. Key features include ¬±5% current-limit accuracy, soft-start control via an external capacitor to minimize inrush current, and an undervoltage lockout (UVLO) for added safety. The MIC2033 also provides a fault status output flag and supports both active-high and active-low logic control for enabling the switch. It is available in compact 6-pin SOT-23 and 6-pin 2mm x 2mm thin DFN packages, making it suitable for space-constrained designs. The operating junction temperature range is from -40¬8C to +125¬8C, making it versatile for various environments. Typical applications include USB peripherals, consumer electronics, and general-purpose power distribution.
