NXP Semiconductors TDA3604TH
The TDA3604Q and TDA3604TH are multiple output voltage regulators with a power switch, intended for use in car radios with or without a microcontroller. It contains one fixed voltage regulator with a foldback current protection (regulator 1) and one fixed voltage regulator (regulator 2), intended to supply a microcontroller, that also operates during load dump and thermal shutdown. The reset and ignition outputs can be used to interface by the microcontroller.| Part No. | TDA3604TH |

FEATURES
General● One VP-state controlled regulator (regulator 2)
● Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown
● Separate control pins for switching regulator 1 and the power switch
● Supply voltage range of −18 to +50 V (operating from 9.75 V)
● Low reverse current of regulator 2
● Low quiescent current (when regulator 1, power switch and ignition buffer are switched off)
● Ignition input/output
● Reset output
● Adjustable reset delay time
● High ripple rejection
● Power switch
● Separate supply for the power switch. Protections
● Reverse polarity safe (down to −18 V without high reverse current)
● Able to withstand voltages up to 18 V at the outputs (supply line may be short-circuited)
● ESD protected on all pins
● Thermal protection
● Load dump protection
● Foldback current limit protection for regulators 1 and 2
● Delayed second current limit protection for the power switch
● The regulator outputs and the power switch are DC short-circuited safe to ground and VP.
