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).
主な特徴
- 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
- Step-down synchronous switching voltage regulator
