The main output supplies loads up to 450 mA and the additional tracked outputs can provide up to 50 mA and 100 mA. In addition the device includes a watchdog for microcontrollersupervision, an undervoltage reset, a power on reset and extended enabling features. The watchdog and reset timing can be chosen independently of each other. The TLE 4471 is available in a Power PG-DSO-20 package. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against overload, short circuit and overtemperature. Of course the TLE 4471 can be used in other applications as well. The TLE 4471 operates in the temperature range of Tj = -40 to 150 °C.

If the input voltage exceeds the 40 V up to 60 V for less than 400 ms, e.g. caused by a load dump, the active components are switched off. For compensating line influences and to avoid steep input edges above 1 V/µs an input capacitor is needed. Using a resistor of approx. 1 Ω in series to the input capacitor, the oscillating circuit consisting of input inductance and input capacitor is damped. Data Sheet 14 Rev. 1.6, 2009-02-03 TLE 4471 Output Voltage To obtain an output voltage of VQ1 = 5 V with an accuracy of 2% at the main output Q1 an input voltage in the range of 5.5 V < VI < 40 V is needed. The main output Q1 supplies 5 V with 450 mA current capability. For stability it requires an output capacitor of at least 22 µF and a maximum ESR of 3 Ω. The two outputs Q2 and Q3 are tracked to Q1 and can supply currents of 100 mA and 50 mA. So any undervoltage condition or shutdown of Q1 will cause the same effect to Q2 and Q3. For Stability both outputs require an output capacitor of at least 10 µF with ESR < 3 Ω each. Q2 is switched on and off simultaneously with Q1, while the tracked output Q3 can be enabled or disabled individually. Two reference outputs REF2, REF3 with voltages of VREF2 = VQ2/2 and VREF3 = VQ3/2 are also available. In case of an overvoltage at the tracker outputs, the voltage references are limited internally to 4.5 V. Output Current The output current is a function of the input voltage. For high input voltages above 22 V, the output current is reduced linear. This is designed into the regulator for protection. Above 42 V the regulator is switched off. The thermal shutdown switches the regulator off, if it exceeds the thermal threshold of 160 °C typical. It is switched on again, as soon as the regulator is cooled down by typical 10 K (thermal hysteresis). Please note the device should not be operated above a junction temperature of 150 °C for long term reliability. Enable Function The TLE 4471 includes the possibility of enabling the main and tracked outputs. Three ORed enable inputs E1, E2, E3 are used to control the main output Q1 and the tracked output Q2. E1 and E3 can be supplied from the battery line or ignition key with input voltages up to 16 V. The enable inputs should be protected by a series resistor and a capacitor, e.g. RE1 = RE3 = 22 kΩ, CE1 = CE3 = 2.2 nF. E2 is intended for connection to the microcontroller. A logic HIGH at any enable input will switch on the related regulator and/or tracker. A separate enabling pin EN is available to switch on and off the second tracked output Q3 separately by the microcontroller. Reset The power on reset feature is necessary for a defined start of the microprocessor during power up. When the output voltage of the main regulator has reached the reset threshold voltage the reset delay capacitor CDR is charged. After a certain time, the reset delay time tdr, the voltage at the capacitor equals the upper reset timing threshold and the reset output goes HIGH. Data Sheet 15 Rev. 1.6, 2009-02-03 TLE 4471 The reset delay time tdr is defined by the reset delay capacitor CDR at pin DR and can be calculated as follows: VDR ,dt t rd = C DR × -------------I DR ,ch Definitions: • • • • (1) CDR = reset delay capacitor tdr = reset delay time required by the application VDR, dt = typical 1.8 V for power up reset IDR, ch = charge current typical 4 µA For a delay capacitor CDR = 100 nF the typical power up reset delay time is 45 ms. The undervoltage reset circuitry supervises the output voltage. In case VQ1 falls below the reset threshold the reset output is set LOW after the reset reaction time trr (discharge of the reset delay capacitor). The reset LOW signal is held down to an output voltage VQ1 of 1 V. Both, the reset reaction time and the reset delay time are defined by the capacitor value. The reset reaction time trr is the time it takes the voltage regulator to set its reset output LOW after the output voltage has dropped below the reset threshold. The reset reaction time can be calculated using the following equation: V DR ,dt – V DR ,st t rr = C DR × ----------------------------------I DR ,dis (2) Data Sheet 16 Rev. 1.6, 2009-02-03 TLE 4471 VΙ VQ V Q, rth < t rr t t VD VDR, dt VDR, st V RO t dr t rr t t Power-on-Reset Thermal Shutdown Voltage Dip at Input Undervoltage Secondary Spike Overload at Output AED03045 Figure 5 Reset Timing The reset output is an open collector output with a pull-up-resistor of typical 4 kΩ to Q1. An external pull-up can be added with a resistor value of at least 20 kΩ. In addition the reset switching threshold can be adjusted by an external voltage divider. The feature is useful with microprocessors which guarantee safe operation down to voltages below the internally set reset threshold of 4.65 typical.

(3) Data Sheet 18 Rev. 1.6, 2009-02-03 TLE 4471 Watchdog The reset and watchdog timing can be defined independently of each other by two delay capacitors CDR and CDW at pins DR and DW. The watchdog function supervises the microcontroller including time base failures. If there is no positive edge within a certain pulse repetition time twp or the trigger pulse is too short a reset is generated. Programming of the max. repetition time is done by a delay capacitor CDW at pin DW. The frequency of the watchdog pulses generated by the microcontroller has to be higher than the minimum pulse sequence twp set by the external reset delay capacitor CDW. The pulse repetition time can be calculated as follows: V DW ,dt – V DW ,st t wp = C DW × ------------------------------------I DW ,ch (4) VI t VQ1 t t > 10 µs VW t VDW,dt t VDW,st VDR,dt VDR,st t > 25 µs tWP VDW VDR tdr VR trr t Missing edge at Watchdog Watchdog pulses too short t AET03000 Figure 7 Watchdog Timing If the watchdog is not used in an application the pin WD has to be connected to GND.
