TDA3609JR
The TDA3609JR is a multiple output voltage regulator with a power switch and ignition buffers, intended for use in car radios with or without a microcontroller. It contains: * Two fixed voltage regulators with a foldback current protection (regulator 1 and regulator 3) and one fixed voltage regulator (regulator 2), intended to supply a microcontroller, that also operates during load dump and thermal shutdown * A power switch with protections, operated by an enable input * Reset and hold outputs that can be used to interface by the microcontroller. The reset-signal can be used to call up the microcontroller and the hold output indicates regulator 1 voltage available and within range. * A supply pin which can withstand load dump pulses and negative supply voltages. * Regulator 2 that will be switched on at a back-up voltage greater than 6.5 V and off when the output voltage of regulator 2 drops below 1.9 V. * A provision for use of a reserve supply capacitor that will hold enough energy for regulator 2 (5 V continuous) to allow a microcontroller to prepare for loss of voltage. * An inverted ignition 1 input with open collector output stage. * An ignition 2 input Schmitt trigger with push pull output stage.

FUNCTIONAL DESCRIPTION The TDA3609JR is a multiple output voltage regulator with a power switch, intended for use in car radios with or without a microcontroller. Because of low-voltage operation of the car radio, low-voltage drop regulators are used in the TDA3609JR. Regulator 2 will switch on when the back-up voltage exceeds 6.5 V for the first time and will switch off again when the output voltage of regulator 2 is below 1.9 V (this is far below an engine start). When regulator 2 is switched on and the output voltage of this regulator is within its voltage range, the reset output will be enabled (reset will go HIGH via a pull-up resistor) to generate a reset to the microcontroller. The reset cycles can be extended by a external capacitor at pin 13. The above mentioned start-up feature is built-in to secure a smooth start-up of the microcontroller at first connection, without uncontrolled switching of regulator 2 during the start-up sequence.
The charge of the back-up capacitor can be used to supply regulator 2 for a short period when the supply falls down to 0 V (time depends on value of storage capacitor). The output stages (regulator 1 and 3) of this regulator have extreme low noise behaviour and good stability. Using small output capacitors regulator 1 and 3 are made stable. When both regulator 2 and the supply voltage (VP > 4.5 V) are available, regulators 1 and 3 can be operated by means of enable inputs (pins 10 and 4 respectively). Regulator 1 has a hold output (open collector) indicating that the output voltage of this regulator is settled (held HIGH by external pull-up resistor). When the output voltage of this regulator drops out of regulation (because of supply voltage drop or high load) the hold output will go LOW. The hold output signal is only valid when regulator 1 is enabled by its enable input (pin 10).

The power switch can also be controlled by means of a separate enable input (pin 11). All output pins are fully protected. The regulators are protected against load dump (regulator 1 and 3 will switch off at supply voltages >18 V) and short-circuit (foldback current protection). The switch contains a current protection, but this protection is delayed at short-circuit condition for at least 10 ms. During this time the output current is limited to a peak value of at least 3 A and 2 A continuous (VP 18 V).
TDA3609JR
At supply voltages >17 V the switch is clamped at maximum 16 V (to avoid external connected circuitry being damaged by an overvoltage) and the switch will switch off at load dump. By means of two independent ignition Schmitt triggers and ignition output buffers (one open collector and one push-pull output), interfacing with the microcontroller can be accomplished (simple full/semi on/off logic applications). The ignition 1 output is inverted. The total timing diagrams are shown in Figs 3 and 4.

Application information NOISE Table 1 Noise figures NOISE FIGURE (V)(1) CO = 10 F CO = 47 F CO = 100 F 1 2 3 Note 1. Measured at a bandwidth of 200 kHz. The noise on the supply line depends on the value of the supply capacitor and is caused by a current noise (output noise of the regulators is translated into a current noise by means of the output capacitors). When a high frequency capacitor of 220 nF in parallel with an electrolytic capacitor of 100 F is connected directly to pins 1 and 14 (supply and ground) the noise is minimal. STABILITY The regulators are made stable with the external connected output capacitors. tbf tbf tbf 150 150 200 tbf tbf tbf
TDA3609JR
The output capacitors can be selected using the graphs of Figs 8 and 9. When an electrolytic capacitor is used, the temperature behaviour of this output capacitor can cause oscillations at a low temperature. The next 2 examples show how an output capacitor value is selected.
REGULATOR
Example 1
Regulators 1 and 3 are made stable with an electrolytic output capacitor of 220 F (ESR = 0.15 ). At -30 C the capacitor value is decreased to 73 F and the ESR is increased to 1.1 . The regulator will remain stable at -30 C.
Example 2
Regulator 2 is made stable with a 10 F electrolytic capacitor (ESR = 3 ). At -30 C the capacitor value is decreased to 3 F and the ESR is increased to 23.1 . Using Fig.9, the regulator will be instable at -30 C.
Solution
Use a tantalum capacitor of 10 F or a larger electrolytic capacitor. To avoid problems with stability at low temperatures, the use of tantalum capacitors is recommended.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values

with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
