L5962
Multiple linear/switching voltage regulator for car-radio
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
Description
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 A max -
40 °C < T < 85 °C) and minimum operating
voltage (4.5 V using an external Schottky diode
for the back-up function).
