Description

This reference design is a smart OR-ing boost converter for automotive emergency call (eCall) applications utilizing a low quiescent current boost controller. The design uses two boost power stages driven by the same controller. The main battery input includes a bypass switch function. The backup battery input has a separate enable with disconnect switches. This combination allows for seamless crossover from the main battery to the backup battery.

Features
  • Dual boost power stages allows for single controller operation
  • 440 kHz switching frequency, which is below the AM band
  • Low input voltage for operation during cold crank
  • Bypass switch for main battery reduces losses
  • Automatic crossover to battery backup for glitch-free performance
