AH8500/1 and AH8502/3 Micropower Linear Hall-Effect Sensors

Diodes' AH850/1/2/3 is a family of low-power / micropower linear Hall-effect sensors with output voltage ratiometric to supply and magnetic field sense range of ±400 G for battery powered consumer, home appliances, and industrial applications.

The high-performance AH8501 and AH8503 have trimmed sensitivity accuracy of 3% with a null voltage offset below 1% of supply voltage. Designed for a wide range of applications, they are optimized for the supply range of 1.6 V to 3.6 V consuming only 8.9 µA in sleep mode (AH8500 / AH8501) and 13 µA in micropower mode (AH8502 / AH8503). The sensors have an ESD rating of 6 kV for robustness.

For system flexibility the enable pin in the AH8500/1 and CNTRL pin on the AH8502/3 allow operating modes and sampling rate to minimize current consumption. In default modes, the AH8500/1 are in sleep mode while AH8502/3 operate in micropower mode. The family of sensors are available in the small low-profile U-DFN2020-6.
