INTEGRATED CIRCUITS DATA SHEET TDA3609JR Multiple voltage regulator with switch and ignition buffers Preliminary specification File under Integrated Circuits, IC01 1997 Aug 15 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch and ignition buffers TDA3609JR FEATURES GENERAL DESCRIPTION General 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: • Extreme low noise behaviour and good stability with very small output capacitors • Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown • 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 • Separate control pins for switching regulator 1, regulator 3 and the power switch • A power switch with protections, operated by an enable input • Supply voltage range of −18 to +50 V • 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. • Two VP-state controlled regulators (regulator 1 and regulator 3) and a power switch • Low reverse current of regulator 2 • Low quiescent current (when regulator 1, regulator 3, and power switch are switched-off) • A supply pin which can withstand load dump pulses and negative supply voltages. • Hold output (only valid when regulator 1 is switched-on) • Reset and hold outputs (open collector outputs) • 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. • Adjustable reset delay time • High ripple rejection • 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. • Back-up capacitor for regulator 2 • Two independent ignition buffers (one inverted and with open collector output). Protections • An inverted ignition 1 input with open collector output stage. • Reverse polarity safe (down to −18 V without high reverse current) • An ignition 2 input Schmitt trigger with push pull output stage. • Able to withstand voltages up to 18 V at the outputs (supply line may be short-circuited) • ESD protected on all pins • Thermal protections with hysteresis • Load dump protection • Foldback current limit protection for regulators 1, 2 and 3 • Delayed second current limit protection for the power switch (at short-circuit) • The regulator outputs and the power switch are DC short-circuited safe to ground and VP.

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). 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. 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. 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. 1997 Aug 15 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). 5 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch and ignition buffers The power switch can also be controlled by means of a separate enable input (pin 11). 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. 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). 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 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).

At −30 °C the capacitor value is decreased to 73 µF and the ESR is increased to 1.1 Ω. The regulator will remain stable at −30 °C. Note 1. Measured at a bandwidth of 200 kHz. Example 2 Regulator 2 is made stable with a 10 µF electrolytic capacitor (ESR = 3 Ω). At −30 °C the capacitor value is decreased to 3 µF and the ESR is increased to 23.1 Ω. Using Fig.9, the regulator will be instable at −30 °C. 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 µF is connected directly to pins 1 and 14 (supply and ground) the noise is minimal. Solution Use a tantalum capacitor of 10 µF or a larger electrolytic capacitor. To avoid problems with stability at low temperatures, the use of tantalum capacitors is recommended.

The total contact time of successive solder waves must not exceed 5 seconds. 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. 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 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). 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. 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 This data sheet contains target or goal specifications for product development.
