MIC2547-2BTS

Overview

The MIC2547-2BTS is a dual programmable current limit switch manufactured by Microchip Technology. It features two independent high-side N-channel power switches in a single package. The device supports an operating voltage range of 2.7V to 5.5V and provides a maximum output current of 1.5A per channel. Key electrical parameters include a maximum on-resistance of 120 milliohms, adjustable current limits ranging from 100mA to 1.5A, a maximum turn-on time of 5ms, and a maximum blanking time of 22us. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual independent high-side power switches with integrated current limiting
• Programmable current limit threshold for precise load protection
• Integrated thermal shutdown and reverse current blocking capabilities

Applications

• Power distribution systems requiring dual channel isolation
• Peripheral power switching in embedded computing platforms
• Industrial control equipment load management

Procurement Notes

Verify the specific suffix 'BTS' corresponds to the TSSOP-16 surface mount package configuration. Confirm RoHS compliance status as documentation may indicate lead-containing variants. Ensure the selected component matches the required current limit programming specifications for the target application circuit design.

Selection Notes

Select this component when dual-channel high-side switching with independent programmable current limits is required. The low on-resistance minimizes power dissipation during normal operation. Verify that the input voltage range aligns with the system supply rails and that the thermal performance meets the ambient operating conditions.

Part Context

This part belongs to the MIC2547 series of power distribution switches. It serves as a compact solution for managing multiple loads in space-constrained designs. The integration of protection features reduces the need for external discrete components, simplifying the overall bill of materials and board layout requirements.
