Philips Semiconductors
Multiple voltage regulator
Product specification
TDA3615J
FEATURES
General
• Six voltage regulators
• Five microprocessor controlled regulators
(regulators 2 to 6)
• Regulator 1 and reset operate during load dump and
thermal shutdown
• Low reverse current of regulator 1
• Very low quiescent current when regulators 2 to 6 and
power switches are switched off (VI(ig) = 0 V)
• Reset output
• Adjustable display regulator
• High ripple rejection
• Three power switches
• Low noise for regulators 2 to 6.
GENERAL DESCRIPTION
The TDA3615J is a multiple output voltage regulator with
power switches, intended for use in car radios with or
without a microprocessor. It contains:
• One fixed voltage regulator (regulator 1) intended to
supply a microprocessor, that also operates during load
dump and thermal shutdown
• 5 power regulators supplied by VI(ig)
• 3 power switches with protections
• 3 enable inputs for selecting regulators 2 to 6 and the
three power switches
• Very low quiescent current of typical 110 µA.
Protections
• Reverse polarity safe (down to −18 V without high
reverse current)
• Able to withstand voltages up to 18 V at the output
(supply line may be short-circuited)
• ESD protected on all pins
• Thermal protection
• Load dump protection
• Foldback current limit protection (except for regulator 2)
• The regulator outputs and the power switches are DC
short-circuited safe to ground and Vbat.
