Sales Briefcase
  • L5962 is a very versatile device exploiting BCD technology characteristics to provide a complete set of regulated voltages covering all the needs of a car-radio set.

    In standby condition the device guarantees extremely low quiescent current (90 μA max -40 ˚C < T < 85 ˚C) and minimum operating voltage (4.5 V using an external Schottky diode for the back-up function).

    Key Features

    • Step-down synchronous switching voltage regulator
      • Internal high-side/ Low-side NDMOS
      • 1.2 < Vout < 8 V selectable through external resistors
      • 1.2/2.5 A load current selected through dedicated pin
      • 185 kHz free-run frequency
      • SYNC function (220 < fsw < 400 kHz)
    • Linear regulators
      • 3.3/5 V @ 150 mA standby regulator selected through dedicated pin (VSTBYSEL)
      • 5/8.5 V @ 350 mA switched linear regulator enabled and selected through I2C bus (VLR1)
      • 3.3/10 V @ 1 A switched linear regulator enabled and selected through I2C bus (VLR2)
    • 2 High side drivers (0.5 V max drop @ 0.5 A) enabled through I2C bus and equipped with protection circuit against:
      • short to ground and battery
      • loss of ground and battery
      • unsupplied short to battery
    • Reset function with configurable delay (RST, RSTDLY)
    • I2C bus
    • Enable pin to drive switching regulator and I2C bus logic
    • Under/over voltage battery detector (VBATVW)
      • Under voltage threshold adjustable through dedicated pin (LVWIN)
    • Load dump protection
    • Independent thermal protection on all regulators
