Key features
  • AEC-Q100 qualified
  • Two step-down synchronous switching voltage regulators with internal power switches:
    • Wide input voltage range (from 3.5 V to 26 V)
    • Internal high-side/ low-side NDMOS
    • 1 V minimum output
    • 3.0 A load current
    • 250 kHz free-run frequency
    • 250 kHz < f < 2 MHz synchronization range
    • Integrated soft-start
    • Independent hardware enable pins
    • Independent power supply
    • 180° PWM output phase shift
    • Programmable switching frequency divider by 1, 2, 4 or 8 between the two DC/DC regulators
    • Power good function
  • One standby / linear regulator
    • Output voltage programmable with external resistor divider
    • 250 mA maximum current capability
    • Backup function
    • Power good function
  • One high side driver
    • 0.5 V max drop @ 0.5 A
    • Protected against short to ground and battery, loss of ground and battery, unsupplied short to battery
  • Programmable under voltage battery detector
    • Under voltage threshold adjustable through dedicated pin (VDIN)
  • Load dump protection
  • Independent thermal protection on all regulators
  • Independent current limit on all regulators
  • Extremely low quiescent current in standby conditions
  • Power good / adjustable voltage detector outputs to realize customized power up/down sequences
