| Mfr. Part # | AH1902-FT4-7 | Package | UTDFN-6-EP(1.5x2) |
| Model Number | AH1902-FT4-7 |
The AH1902 is a high-sensitivity, micropower Omnipolar Hall-effect switch IC designed for portable and battery-powered consumer electronics, as well as office equipment, home appliances, and industrial applications. It features internal pull-up and pull-down capability, an average supply current of 4.3A at 1.8V, and operates over a supply range of 1.6V to 3.6V. Its hibernating clocking system minimizes power consumption, and it is available in compact packages to save PCB space. The output activates with either a north or south magnetic pole, turning on when the magnetic flux density exceeds the operate point (Bop) and holding until it drops below the release point (Brp).
