MIC94300YCS-TR

Overview

The MIC94300YCS-TR is a single-channel N-channel power switch IC from Microchip Technology, housed in a compact 4-WLCSP (0.88x0.88 mm) package. It features an input voltage range of 1.8 V to 3.6 V and supports a continuous output current of 200 mA with a current limit of 315 mA. The device incorporates Ripple Blocker™ technology for active noise filtering and includes a maximum turn-on time of 150 µs. It operates within a temperature range of -40°C to +125°C and utilizes a non-inverting control interface.

Feature Summary

• Integrates Micrel's Ripple Blocker™ active filter technology for high-efficiency noise suppression in sensitive data and image capturing systems.
• Functions as an integrated load switch with a single output channel and non-inverting input type.
• Provides precise current limiting capabilities to protect downstream components from overcurrent conditions.

Applications

• Noise-sensitive data acquisition systems
• Image capturing systems requiring clean power rails
• Portable electronic devices with strict space constraints

Procurement Notes

Verify the specific manufacturer source, as this component was originally developed by Micrel before its acquisition by Microchip Technology. Confirm that the datasheet references the correct legacy branding if required for compliance documentation. Ensure the 4-WLCSP footprint matches your PCB design requirements precisely.

Selection Notes

Select this component when active ripple blocking is necessary for signal integrity in low-voltage applications. The 4-WLCSP package offers a small form factor suitable for dense layouts. Consider the 1.8 V to 3.6 V operating range to ensure compatibility with your system's supply voltage.

Part Context

This part belongs to the MIC94300 series of load switches designed for power distribution. It is distinct from other variants like the MIC94300YMT-TR due to its specific WLCSP packaging. The series is engineered for applications where power rail cleanliness and rapid switching are critical performance factors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference availability through official Microchip channels or authorized distributors for equivalent specifications.
