The bipolar Hall ICs BU52001GUL, BU52011HFV, BU52021HFV, BU52015GUL, BU52025G, BU52051NVX, BD7411G can operate both S- and N-pole, and the output goes from Hi to Low. These products feature micropower operation, ultra-compact package, high ESD resistance, etc.
The document introduces ROHM's bipolar Hall IC series, which act as magnetic switches with both S‑ and N‑pole operation. It lists the various package types, supply‑voltage options, and dual‑output options, and outlines typical applications such as mobile phones, notebook computers, and digital cameras.
Detailed electrical characteristics are provided for each part, including supply voltage ranges, output current limits, power dissipation, operating temperature ranges, hysteresis, and measurement circuit examples. Guidance on handling strong light exposure and power‑source design for intermittent operation is also included.
