Product overview

Description

The L5959 contains a four voltage regulator and two protected HSDs. HSDs are protected against loss of ground and loss of battery.

The IC includes a monitoring circuit for detection.

The IC features a very low quiescent current in stand-by and independent thermal shutdown.

  • All features

    • Four outputs
      • 8.5V @ 200mA (V8P5)
      • 8/10V @ 1000mA selectable 10V or 8V (V810)
      • 3.3V @ 100mA permanent (VSTBY)
      • 3.3V @ 800mA (VREGSW)
    • Two protected high side driver (HSD1, HSD2)
    • Reset function
    • Battery voltage (under/over) warning output
    • Load dump protection
    • Independent thermal shutdown on all regulators and HSDs
    • Overcurrent limitation
    • Storage CAP output (STCAP)
    • Small CAP required by stability of regulators
    • All pins ESD protected
