A1229 - Hall-Effect Latch

This page provides the datasheet information for the A1229, a member of the A1225 Hall-Effect Latch family.

Description

These Hall-effect latches are extremely temperature-stable and stress resistant sensor ICs especially suited for operation over extended temperature ranges to 150°C.

Features

  • Symmetrical switchpoints.
  • Superior temperature stability.
  • Operation from unregulated supply.
  • Open-drain 25 mA output.
  • Reverse battery protection.
  • Activate with small, commercially available permanent magnets.
  • Solid-state reliability.
  • Small size.
  • Resistant to physical stress.
  • Enhanced ESD structures result in 8 kV HBM ESD performance without external protection components.
  • Internal protection circuits enable 40 V load dump compliance without.
