MIC2043-1BTS

Overview

The MIC2043-1BTS is a single-channel high-side power switch IC from Microchip Technology, designed for load distribution and protection in low-voltage systems. It operates within an input voltage range of 0.8 V to 5.5 V and supports a continuous output current of up to 500 mA with a programmable current limit adjustable between 0.5 A and 3 A. The device features a typical on-resistance of 60 mΩ and includes integrated fault protection mechanisms such as overcurrent, overtemperature, and reverse current blocking. Packaged in a 14-pin TSSOP surface-mount case, it functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Integrates high-side switching capability with built-in overcurrent, overtemperature, and reverse current protection for robust load management.
• Features a low on-resistance path to minimize power loss and heat generation during normal operation.
• Supports programmable current limiting to allow customization of protection thresholds based on specific application requirements.

Applications

• USB hub port power switching and protection
• Peripheral device power distribution in embedded systems
• Hot-swap applications requiring controlled turn-on and fault isolation

Procurement Notes

Verify the exact suffix 'BTS' corresponds to the 14-TSSOP package and tube packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Microchip sales representatives. Ensure the selected variant matches the required thermal performance and pinout for the target PCB layout.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection is required for loads operating between 0.8 V and 5.5 V. Consider the MIC2043-1BTS if the application demands a compact 14-TSSOP footprint and programmable current limiting. Evaluate thermal dissipation requirements given the 60 mΩ on-resistance at maximum load conditions.

Part Context

The MIC2043 series belongs to Microchip's family of USB power switches and load drivers. This specific part represents the single-channel variant within the MIC2043 lineup, offering a balance of integration and protection features suitable for portable electronics and industrial control interfaces where space efficiency and reliability are critical.

Replacement Considerations

Direct substitutes include other single-channel variants from the MIC2043 family, such as the MIC2043-1YM or MIC2043-1BM, provided the package type and electrical specifications align with the design requirements. Cross-referencing datasheets is essential to ensure compatibility in terms of current limits and protection thresholds.
