Overview
The MIC2043-1YM-TR is a single-channel high-side power switch IC from Microchip Technology, designed for low-voltage distribution applications. 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 maximum on-resistance of 60 mΩ and includes integrated protection against overcurrent, overtemperature, and undervoltage lockout (UVLO). Packaged in an 8-pin SOIC, it functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated high-side switching capability with low on-resistance for efficient power distribution
- Programmable current limit allowing adaptation to various load requirements
- Comprehensive fault protection including overcurrent, thermal shutdown, and undervoltage lockout
Applications
- USB port power management and distribution
- Peripheral circuit protection in consumer electronics
- Battery-powered device load switching
Procurement Notes
Verify the specific suffix 'YM-TR' confirms the 8-pin SOIC package and tape-and-reel shipping format. Ensure the order matches the required current limit configuration, as the base part number allows for variable limits. Confirm RoHS compliance status if restricted substances are a constraint for your assembly process.
Selection Notes
Select this component when a single-channel high-side switch with low voltage operation is required. It is suitable for applications needing precise current limiting and robust fault protection. Consider the 8-pin SOIC package constraints regarding board space and thermal dissipation capabilities relative to the expected load current.
Part Context
This part belongs to the MIC2043 family of USB power switches. It shares architectural similarities with other members like the MIC2042 and MIC2043-1YTS but differs in package type and channel count. The family is designed for cost-effective power distribution in portable devices requiring reliable load control.
Replacement Considerations
Direct substitutes include MIC2043-1YM or MIC2043-1BM-TR, which share identical electrical characteristics and pinouts. Verify that any alternative maintains the same SOIC-8 footprint and current limit specifications to ensure compatibility.
