A1184 Datasheet | Allegro MicroSystems

Features and Benefits - Chopper stabilization ▫ Low switchpoint drift over operating temperature range ▫ Low sensitivity to stress - Field programmable for optimized switchpoints - On-chip protection ▫ Supply transient protection ▫ Reverse-battery protection ▫ On-board voltage regulator ▫ 3.5 to 24 V operation Packages: 3 pin SOT23W (suffix LH), and 3 pin SIP (suffix UA) Description The A1184 device is a standard, two-wire, unipolar, Hall effect switch. The operate point, BOP, can be field-programmed, after final packaging of the device and placement into the application. This advanced feature allows the optimization of the device switching performance, by effectively accounting for variations caused by mounting tolerances for the device and the target magnet. This device is produced on the Allegro Micro Systems advanced Bi CMOS wafer fabrication process, which implements a...
