Overview
The MIC2042-1YM-TR is a single-channel high-side power switch IC from Microchip Technology, designed for USB power distribution applications. It operates within an input voltage range of 1.6V to 5.5V and supports a maximum output current of 3A. The device features a typical on-resistance of 40 milliohms and includes integrated fault protection mechanisms such as adjustable current limiting, overtemperature shutdown, undervoltage lockout (UVLO), and open-load detection. It is housed in an 8-SOIC surface-mount package and functions across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates adjustable current limiting with open-load detection capabilities
- Provides controlled slew rate management to minimize inrush current
- Includes status flag output for monitoring operational state
Applications
- USB hub power switching
- Peripheral power distribution
- Hot-swap circuitry
Procurement Notes
Verify the specific suffix 'YM' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering code matches the required tape-and-reel packaging format. Cross-reference the component marking with the latest production change notices to avoid counterfeit or obsolete variants.
Selection Notes
Select this component when a single high-side switch with adjustable current limit and open-load detection is required. It is suitable for low-voltage applications up to 5.5V where controlled turn-on characteristics are necessary. Compare against the MIC2042-1YTS variant if tube packaging is preferred instead of reel packaging.
Part Context
This part belongs to the MIC2042 series of USB power switches. It serves as a high-side driver that protects downstream loads from overcurrent and thermal faults. The device is commonly used in portable electronics and computer peripherals requiring robust power management and fault signaling.
Replacement Considerations
MIC2042-1YTS-TR: Identical electrical specifications but supplied in tube packaging rather than tape-and-reel.
FAQ
Does the MIC2042-1YM-TR support open-load detection?
Yes, the device includes built-in open-load detection functionality.
What is the maximum input voltage for this switch?
The maximum input voltage rating is 5.5V.
