Overview
The MIC2042-2BM-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a single N-channel output with a typical on-resistance of 425 milliohms and a current limit of 150 mA. The device operates within an input voltage range of 3V to 5.5V and supports temperatures from -40°C to +85°C. Packaged in a 16-SOIC surface-mount case, it includes fixed current limiting and overtemperature fault protection.
Feature Summary
- Integrates fixed current limiting and overtemperature protection for load safety
- Provides controlled slew rate to minimize inrush current during turn-on
- Features status flag output for monitoring switch conditions
Applications
- USB port power switching applications
- Peripheral circuit protection in consumer electronics
- Load driver circuits requiring thermal management
Procurement Notes
Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the 16-SOIC package dimensions match the target PCB footprint. Ensure the 150mA current limit aligns with the specific load requirements, as this parameter differs from other variants in the series.
Selection Notes
Select this part when a single-channel high-side switch with integrated thermal protection is required. The 16-SOIC package offers a balance of pin count and board space. Consider the 150mA current limit and 425mΩ resistance against system power budget constraints. Verify compatibility with control logic levels for the non-inverted input interface.
Part Context
This component belongs to the MIC2042/MIC2537 family of power switches designed for low-voltage distribution. While sharing similar protection features like overtemperature sensing, the MIC2042-2BM-TR is distinguished by its single-channel configuration and specific 16-SOIC packaging, differing from multi-channel or TSSOP variants in the broader product line.
Replacement Considerations
The MIC2537-2YM-TR is identified as a direct substitute for the MIC2537-2BM-TR; however, cross-referencing between the MIC2042 and MIC2537 families requires careful verification of pinout and electrical specifications.
