Overview
The MIC94071YMT-TR is a high-side power switch from Microchip Technology, designed for power distribution applications. It features a P-channel output capable of handling a maximum continuous current of 1.2A with an on-state resistance of 0.12Ω. The device operates within an input voltage range of 1.7V to 5.5V and supports non-inverted logic control. Packaged in a compact 4-TMLF (1.2x1.6mm) surface-mount format, it functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- High-side load switching capability with P-channel architecture
- Compact 4-terminal ultra-small footprint package design
- Non-inverted logic interface for direct control integration
Applications
- Portable electronic device power management
- Peripheral circuit protection and distribution
- Battery-powered system load switching
Procurement Notes
Verify the specific datasheet revision when sourcing, as Microchip acquired Micrel, potentially affecting documentation numbering. Confirm the 4-TMLF package dimensions match your PCB footprint requirements precisely. Ensure the non-inverted logic level aligns with your system's control voltage standards before finalizing procurement orders.
Selection Notes
Select this component for applications requiring low-profile packaging and moderate current handling up to 1.2A. Compare against the MIC94072YMT-TR if inverted logic is preferred, or the MIC94073YMT-TR for higher current capabilities. Ensure the 0.12Ω on-resistance meets thermal dissipation constraints for your specific load profile and ambient temperature conditions.
Part Context
This part belongs to the MIC94070-73 series of high-side power switches. It shares the same family characteristics as the MIC94072YMT-TR and MIC94073YMT-TR, differing primarily in logical inversion and current ratings. The series is widely used in portable electronics where space efficiency and reliable power distribution are critical design parameters.
Replacement Considerations
The MIC94072YMT-TR serves as a functional substitute if inverted logic control is acceptable. Verify pinout compatibility and thermal performance similarities before swapping components in existing designs.
