TMA445A-44LQI35ZZT

Overview

The TMA445A-44LQI35ZZT is a TrueTouch Gen4X capacitive touchscreen controller manufactured by Infineon Technologies (formerly Cypress Semiconductor). It features a 36-sense I/O configuration supporting displays up to 5 inches. The device utilizes 15V Tx drives for high signal-to-noise ratio and includes Charger Armor technology for noise immunity. Key functional capabilities include glove touch, face detection, and hover support. It operates with a low power consumption of 4.5 uW in deep sleep mode.

Feature Summary

TrueTouch Gen4X architecture with 15V Tx drive capability
Charger Armor adaptive noise suppression technology
Supports glove touch, face detection, and hover sensing
Low power deep sleep mode at 4.5 uW

Applications

Mobile handsets requiring glove and face detection
Tablets and small display devices up to 5 inches
Applications demanding high charger noise immunity

Part Context

This component belongs to the TrueTouch Gen4X family of touchscreen controllers. Within this family, the TMA445A variant specifically adds face detection and hover capabilities compared to the standard TMA445 model, while maintaining the same 36-sense I/O count and 15V drive voltage specifications.

Replacement Considerations

The standard TMA445 serves as a related part within the same family but lacks face detection and hover support. Selection between these models depends on whether advanced proximity and face-detection features are required for the specific application design.
