This means a single magnet orientation works for lid-close detection, rotation sensing, or proximity triggers — no need to align pole direction on the assembly line. The CMOS output swings rail-to-rail and sinks or sources up to 500 µA, enough to drive a GPIO or a small load directly. Maximum quiescent supply current is just 8 µA, making this a candidate for always-on sensing in battery-operated devices like portable electronics, IoT endpoints, and wearable accessories. ## Package reality: 4-bump CSPBGA The BU52097GWZ- comes in a 4-XFBGA / CSPBGA package — essentially four solder bumps on a 0.5 mm or finer pitch. This is a tiny footprint (roughly 0.9 mm x 0.9 mm body) that saves board area but demands X-ray inspection for solder-joint verification and a controlled reflow profile. No exposed pad to stitch; the bumps carry both signal and mechanical attachment. If your rework lab isn't set up for BGA-style parts, factor in the assembly learning curve or a pre-programmed pick-and-place service. ## Sourcing and lifecycle ROHM lists the BU52097GWZ- as Active in production. The part is ROHS3 compliant, which satisfies EU and most global environmental requirements without an exemption expiry.","metaTitle":"BU52097GWZ-E2 Hall Effect Omnipolar Switch, 1.65V-3.6V","metaDescription":"ROHM BU52097GWZ-E2 omnipolar Hall switch with ±17mT trip, 8µA supply max, 1.65V-3.6V range, 4-XFBGA package.
