Introduction

HS6604 is a high-performance IC integrating single-cell lithium-ion battery charge management and pyroelectric sensing functions. Paired with a pyroelectric infrared sensor and minimal external components, it forms a passive pyroelectric infrared switch — ideal for portable applications compatible with USB power supplies and adapter power sources. It enables automatic, rapid activation of incandescent lamps, fluorescent lamps, buzzers, automatic doors, electric fans, dryers, automatic washbasins, and similar devices. It is particularly suited for sensitive areas such as aisles and corridors in enterprises, hotels, shopping malls, warehouses, and residences, as well as automatic lighting, illumination, and alarm systems in security zones.
