Introduction

The APS11700 and APS11760 families of micropower Halleffect switches are AEC-Q100 qualified for 24 V automotive applications and compliant with ISO 26262:2011 ASIL A (pending confirmation). These sensors are temperature-stable and suited for operation over extended junction temperature ranges up to 165 ℃. This family of Hall-effect switches features a micropower regulator that draws as little as 6 μA of current. The micropower regulator of these devices are designed for harsh automotive and industrial environments and features on-board overvoltage and reverse connection protection. The APS11700 and APS11760 are especially suited for direct battery connection for automotive and industrial applications up to 24 V. The APS11700 and APS11760 families are available in several different magnetic sensitivities and polarities to offer flexible options for system design. They are available in active high and active low variants for ease of integration into electronic subsystems. The APS11700 features a Hall-effect element that is sensitive to magnetic flux perpendicular to the face of the IC package. The APS11760 features a vertical Hall-effect sensing element sensitive to magnetic flux parallel to the face of the IC package. The devices include on-board protection for operation directly from an automobile battery, as well as protection from shorts to ground by limiting the output current until the short is removed. The device is especially suited for operation from unregulated supplies. Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified 3-pin SOT23W surfacemount package, while package type UA is a 3-pin ultramini SIP for through-hole mounting. Both packages are lead (Pb) free, with 100% matte-tin-plated leadframes.
