TLE6712 - Dual Firing Airbag IC

Description

This IC provides four independent actuator channels for firing loops in an safety restraint airbag system.

Each channel is equipped with full diagnostic functions.

interface pins.

Features

  • Two independent squib channels each consisting of a high- side & a low-side switch.
  • Thermal and short circuit protection for each switch.
  • Current limitation for each firing loop.
  • Firing current detection P-DSO-24-1.
  • Voltage measurements.
  • Squib leakage detection to ground and to battery.
  • Precise squib resistance measurement with programmable gain.
  • Multiplexed analog output pin for measurement retrieval.
  • Unid.
