MIC2507BM TR

Overview

The MIC2507BM TR is a quad integrated high-side power switch manufactured by Micrel. It comprises four protected N-channel MOSFET output pass transistors, each with a dedicated TTL-compatible input and charge pump. The device operates within a supply voltage range of 2.7V to 7.5V. Key electrical characteristics include a typical on-resistance of 120mΩ at 5V and 130mΩ at 3.3V. It features current limit protection, thermal shutdown, and an open-drain fault flag. The off-state current is less than 1µA, and the typical rise time is 1ms.

Feature Summary

• Integrates four protected N-channel MOSFETs with dedicated inputs and charge pumps
• Provides current limit protection and thermal shutdown capabilities
• Features an open-drain fault flag for status monitoring
• Ensures low off-state leakage current below 1µA

Applications

• Battery management systems
• General power management circuits

Procurement Notes

Verify component authenticity through authorized Microchip distributors or official channels. Confirm that the specific suffix matches the required package and tape-and-reel specifications. Check for RoHS compliance status as indicated in the latest datasheet revision. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage prior to assembly.

Selection Notes

Select this component for applications requiring multiple independent high-side switches in a compact footprint. It serves as a replacement for discrete high-side drivers and MOSFETs in low-voltage environments. Consider the 120mΩ on-resistance for efficiency calculations. Verify TTL compatibility for control logic interfacing before finalizing the design.

Part Context

The MIC2507 belongs to the Micrel/Microchip family of integrated high-side switches. This series consolidates multiple power switching functions into a single IC to reduce board space and component count. The manufacturer has transitioned from Micrel to Microchip Technology, which continues to support these legacy products.
