Overview
The MIC2033-12BYMT-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a fixed current limit of 1.2A and an operating input voltage range from 2.5V to 5.5V. The device includes thermal shutdown protection, undervoltage lockout (UVLO), and a fault status output flag with a built-in 32ms delay. It offers ±5% current limit accuracy and low quiescent current of 100µA typical when switched on. The component utilizes a 6-pin SOT-23 or 2mm x 2mm DFN package and operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- High-accuracy current limiting with ±5% tolerance for reliable system protection
- Integrated thermal shutdown and undervoltage lockout mechanisms
- Fault status output flag with configurable 32ms delay assertion
- Capacitor-adjustable soft-start circuit to minimize inrush current
Applications
- Power distribution in portable electronic devices
- Overcurrent protection for peripheral circuits
- System reliability enhancement in embedded applications
- Hot-swap control for high-capacitive loads
Procurement Notes
Verify the specific suffix BYMT against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with active-high or active-low logic requirements. Cross-reference the 1.2A current limit setting with application load profiles. Confirm RoHS compliance status through manufacturer datasheets prior to procurement.
Selection Notes
Select this component for applications requiring precise high-side switching with integrated fault management. The 1.2A limit suits moderate load protection needs. Consider the 2.5V to 5.5V supply range for compatibility with standard logic levels. Evaluate the soft-start capability if driving large capacitive loads to prevent voltage droop during startup phases.
Part Context
The MIC2033 series represents a family of high-side MOSFET power switches designed for increased system reliability. This specific variant provides a 1.2A fixed current limit option alongside other available ratings such as 0.5A, 0.8A, and 1A. The series is pin-compatible with earlier models like the MIC2005, facilitating design upgrades.
Replacement Considerations
Direct substitutes include other MIC2033 variants with different current limits (e.g., MIC2033-05, MIC2033-08, MIC2033-10) if load requirements differ. Verify pin compatibility with MIC2005 series components for legacy board replacements.
