CT8122 - Integrated Bipolar TMR Digital Latches

General Description

The CT812x series of bipolar tunnel magnetoresistance (TMR) digital latches are designed for consumer and industrial applications.

The devices are based on Allegro patented XtremeSense™ TMR technology with integrated CMOS process to provide a monolithic solution for superior sensing performance.

Key Features

  • Sensitivity with BOP as low as 10 G.
  • Ultra-low power consumption: ~2.4 µA @ VDD = 3.3 V and fS = 500 Hz.
  • Supply voltage range: 1.7 V to 5.5 V.
  • Sensor polarity: bipolar.
  • Digital CMOS outputs:.
  • Push-pull.
  • Undervoltage lockout (UVLO).
  • 3-lead SOT23 package.
