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 µA max -

40 °C < T < 85 °C) and minimum operating

voltage (4.5 V using an external Schottky diode

for the back-up function).
