MIC2514BM5-TR

Overview

The MIC2514BM5-TR is a high-side power distribution switch manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 3.6V and draws a typical supply current of 70mA. The device supports an output current up to 1.2A with a typical on-resistance (Rds On) of 950mOhm. It features fixed current limiting and over-temperature fault protection. The component is housed in a compact SOT-23 or SC-74A package, suitable for surface-mount assembly.

Feature Summary

• Integrated high-side switch with TTL-compatible input
• Fixed current limiting and over-temperature protection
• Low on-resistance for efficient power delivery

Applications

• Portable electronic devices requiring power management
• Peripheral port protection circuits
• Battery-powered systems needing load switching

Procurement Notes

Verify the specific package variant (SOT-23 vs SC-74A) against the datasheet, as pinout and thermal characteristics may differ between these physical form factors. Confirm that the operating temperature range meets your system requirements. Ensure the input logic levels are compatible with your control signals before finalizing the design.

Selection Notes

Select this component when a compact, low-cost solution for single-channel high-side switching is required. Consider the 950mOhm on-resistance for power loss calculations at full load. Verify that the fixed current limit threshold aligns with the protected circuit's maximum safe operating current to prevent nuisance tripping.

Part Context

This part belongs to the 'IttyBitty' series of integrated high-side switches from Microchip Technology. These components are designed for space-constrained applications where simple, reliable power switching is needed without complex configuration. The TR suffix indicates a tape-and-reel packaging format for automated assembly.
