L5962:Voltage regulator with dc-dc plus switchable linear regulators controlled by I2C bus

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 I2 C bus (VLR1)
    • 3.3/10 V @ 1 A switched linear regulator enabled and selected through I2 C bus (VLR2)
  • 2 High side drivers (0.5 V max drop @ 0.5 A) enabled through I2 C 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)
  • I2 C bus
  • Enable pin to drive switching regulator and I2 C bus logic
  • Under/over voltage battery detector (VBATVW)
    • Under voltage threshold adjustable through dedicated pin (LVWIN)
