Miniature patch-type pressure-sensing chip

Main Features:

This series comprises miniature patch‑type pressure‑sensing chips specifically developed for the medical and healthcare sector. Featuring a transparent protective cover and a standard SMT surface‑mount package, they can be directly mounted onto PCBs via reflow soldering. Equipped with a high‑precision piezoresistive pressure‑sensing element and an integrated temperature‑compensation circuit, these chips accurately measure gas or liquid pressure. They are widely suited to meet the pressure‑monitoring and control requirements of compact portable monitoring devices, respiratory equipment, infusion pumps, and home‑use medical instruments.

Core Features

Medical-grade high precision and stability It employs a medical-grade piezoresistive sensing element, offering minimal temperature drift and excellent long-term stability. Within a wide temperature range, it delivers stable, high-precision pressure measurements, providing reliable pressure data support for medical devices.
Transparent protective cover design for enhanced protection. : Equipped with a transparent protective cover, it effectively safeguards the sensor element from external contamination and mechanical damage, while facilitating optical inspection during production, thereby enhancing product reliability and yield.
Miniature, low-power, surface-mount design, compatible with portable devices. It employs a miniature SMT surface-mount package, offering a compact footprint and enabling direct reflow soldering. With low operating current, it aligns with the trend toward miniaturization and low power consumption in portable medical devices and battery-powered instruments.
Standard SMT package, easy to manufacture. It adopts industry-standard chip‑scale packaging and pad definitions, enabling direct integration with SMT manufacturing processes without additional steps, thereby reducing equipment integration complexity and production costs, and supporting large‑scale mass production.
