The device is available in two packages the PG-DSO-14 and PG-DSO-20. It is designed to supply microprocessor systems under the severe conditions of automotive applications and is therefore equipped with additional protection functions against overload, short circuit and overtemperature. Of course the TLE 4470 can also be used in other applications where two stabilized voltages are required. The device operates in the wide junction temperature range of -40 °C to 150 °C. The stand-by regulator transforms an input voltage VI in the range of 5.6 V ≤ VI ≤ 45 V to VQ1,nom = 5 V within an accuracy of 2%, whereas the main regulator is adjustable. By Type Package TLE 4470 GS PG-DSO-14 TLE 4470 G PG-DSO-20 Data Sheet 1 Rev. 1.2, 2008-03-20 TLE 4470 use of an external voltage divider the main output voltage can be set to VQ2 ≥ 5 V for the TLE 4470 G type (PG-DSO-20 package). VQ1 is compared to the voltage at pin ADJ2, which is proportional to the output voltage VQ2. A control amplifier drives the base of the series PNP transistor via a buffer. The main output voltage VQ2 is tracked to the accuracy of the stand-by output. For the TLE 4470 GS (PG-DSO-14 package) the output voltage is fixed to 5 V. To save energy e.g. in battery powered body electronic applications, the main regulator can be switched off via the disable input, which causes the current consumption to drop to 180 µA typical. Two additional features of the TLE 4470 are an early warning comparator (can be used e.g. to monitor the supply voltage VI) and reset generator with an adjustable reset delay time. The TLE 4470 G (PG-DSO-20 package) has in addition an adjustable reset switching threshold. This feature is useful with microprocessors which guarantee a safe operation down to voltages below the internally set reset threshold of 4.65 V typical. Two functions are included in the reset generator, a power-on-reset and an undervoltage reset. The power-on-reset feature is necessary for a defined start of the microprocessor when switching on the application. The reset signal is kept low for a certain delay time after the output voltage VQ1 of the regulator has surpassed the reset threshold. An external delay capacitor sets this delay time. The under voltage reset circuit supervises the stand-by output voltage. In case VQ1 falls below the reset switching threshold the reset output is set LOW after a short reaction time. The reset LOW signal is generated down to an output voltage VQ1 of 1 V.

Using a resistor of approx. 1 Ω in series with CI, the LC circuit of input inductivity and input capacitance can be damped. To stabilize the regulation circuits of the stand-by and main regulator, output capacitors CQ1 and CQ2 are necessary. Stability is guaranteed at values CQ1 ≥ 6 µF and CQ2 ≥ 10 µF, both with an ESR ≤ 10 Ω within the operating temperature range. For the TLE 4470 G (PG-DSO-20) the output voltage VQ2 of the main regulator can be adjusted to 5 V ≤ VQ2,nom ≤ 20 V by connecting an external voltage divider to the voltage adjust pin ADJ2. For VQ2 = 5 V the voltage adjust pin has to be connected directly to the main output. For calculating VQ2 or R1 and R2 respectively the following equations can be used: VQ2 = VQ1 × (1 + R1 / R2) (1) or R1 = R2 × (VQ2 / VQ1 - 1) (2) Disable The main regulator of the TLE 4470 can be switched OFF by a voltage above 2.3 V at pin DIS. Reducing this voltage below 1.4 V will switch ON the main regulator again. Reset Timing The power-on reset delay time is defined by the charging time of an external capacitor CD which can be calculated as follows: CD = (∆t × ID,c) / ∆V (3) Definitions: CD = delay capacitor ∆t = reset delay time ID,c = charge current, typical 5 µA ∆V = VDU, typical 1.8 V VDU = upper delay switching threshold at CD for reset delay time The reset reaction time trr is the time it takes the voltage regulator to set the reset out • • • • • LOW after the output voltage has dropped below the reset threshold. It is typically 2 µs for delay capacitor of 100 nF. For other values for CD the reaction time can be estimated using the following equation: trr ≈ 20 s/F × CD Data Sheet (4) 14 Rev. 1.2, 2008-03-20 TLE 4470 VΙ t < t rr VQ V Q, rt d V Ι D,c = dt CD VD t V DU V DL VRO t rr t rd t t Power-on-Reset Figure 4 Thermal Shutdown Voltage Dip at Input Undervoltage Secondary Spike Overload at Output AED03010_4470 Reset Timing Reset Switching Threshold The internally set reset threshold is 4.65 V. When using the TLE 4470 G (PG-DSO-20) this threshold can be adjusted to 3.5 V < VQ, rt < 4.6 V by connecting an external voltage divider to pin RADJ. If this pin is not needed, it can be left open or even better connected to GND. R1 = R2 × (VQ, rt - Vref) / Vref or VQ, rt = Vref (1 + R1 / R2) (5) Definitions: • • VQ, rt = Reset threshold Vref = comparator reference voltage, typical 1.35 V (Reset adjust input current ≈ 50 nA) The reset output pin is internally connected to the stand-by output Q1 via a 30 kΩ pull-up resistor. The reset LOW signal at pin RQ is guaranteed down to an output voltage VQ1 of 1 V typical. Data Sheet 15 Rev. 1.2, 2008-03-20 TLE 4470 VQ1 V I1 30 k Ω Band-Gap Reference 1.35 V RO Band-Gap Reference 1.35 V <_ 1 + _ R1 RADJ TLE 4470 G GND Vref R2 AES02505_4470 Figure 5 Early Warning The early warning function compares a voltage defined by the user to an internal reference voltage. Therefore the voltage to be supervised has to be scaled down by an external voltage divider in order to compare it to internal sense threshold (reference voltage) which is typically 1.35 V. The sense out pin is set to low when the user defined voltage falls below this threshold. A typical example where this circuit can be used is to supervise the input voltage VI to give the microprocessor a prewarning of a low battery condition. Calculation of the voltage divider can be easily done since the sense input current can be neglected. The equations needed for calculation are identical to the previously given ones. To minimize transient influences the use of a capacitor in parallel to R2 is recommended. Like the reset output pin, the sense out pin SQ is internally connected to the stand-by output Q1 via a 30 kΩ pull-up resistor. The sense out LOW signal at pin SQ is generated down to an input voltage VI1 of 3 V typical.
