A1148 - (A1147 / A1148) Low Current Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches

Download the A1148 datasheet PDF. This datasheet also covers the A1147 variant, as both devices belong to the same (a1147 / a1148) low current ultrasensitive two-wire chopper-stabilized unipolar hall effect switches family and are provided as variant models within a single manufacturer datasheet.

Description

The A1147 and A1148 devices are two-wire, unipolar, Hall effect switches that are factory-programmed at end-of-line to optimize ultrasensitive magnetic switchpoint accuracy.

Features

  • Chopper stabilization ▫ Low switchpoint drift over operating temperature range ▫ Low sensitivity to stress.
  • Factory programmed at end-of-line for optimized switchpoints.
  • On-chip protection ▫ Supply transient protection ▫ Reverse-battery protection ▫ On-board voltage regulator ▫ 3.5 to 24 V operation.
