BU21170MUV-E2

Overview

The BU21170MUV-E2 is a capacitive switch controller IC manufactured by ROHM Semiconductor. It supports up to five sensors and utilizes a two-wire serial interface for communication. The device is designed for touch sensor applications, integrating the necessary control logic for capacitive detection within a VQFN-20 package.

Feature Summary

• Capacitive sensing capability for multiple touch points
• Two-wire serial interface for system integration
• Integrated controller logic for sensor management

Applications

• Capacitive touch panel controllers
• Consumer electronics with touch input interfaces
• Appliance control panels requiring capacitive switches

Procurement Notes

This component is officially listed as End-of-Life (EOL). Distribution channels indicate that inventory is unavailable and the product has been discontinued. Verification of current stock status through authorized distributors is required, though availability is confirmed as non-existent in standard supply chains.

Selection Notes

Designers should consider this part obsolete due to its EOL status. Alternative capacitive touch controllers from the same manufacturer or other vendors should be evaluated for new designs. Existing implementations may require redesign if long-term supply continuity is a requirement.

Part Context

The BU21170MUV-E2 belongs to ROHM's line of analog circuits focused on user interface controls. It is specifically categorized under capacitive switch controllers, distinct from motor drivers or power management ICs also produced by the manufacturer.
