data sheet 12 rev. 1.0, 2010-11-30 TLE4699 voltage regulator 5 voltage regulator 5.1 description voltage regulator the output voltage v q is controlled by comparing a portion of it to an internal reference and driving a pnp pass transistor accordingly. saturation cont rol as a function of the load current prevents any oversa turation of the pass element. the control loop stability depends on the ou tput capacitor c q , the load current, the chip temperature and the poles/zeros introduced by the integrated circuit. to ensure stable operation, the output capacitor?s capacitance and its equivalent series resistor esr requirements given in the table ? ?functional range? on page 10 have to be maintained. for details see also the typical per formance graph ?output capac itor series resistor esr cq vs. output current i q ?. also, the output capacitor shall be sized to buffer load transients. an input capacitor c i is not needed for the control loop stability, but recommended to bu ffer line influences. connect the capacitors close to the ic terminals. protection circuitry prevent the ic as well as the application fr om destruction in case of catastrophic events. these safeguards contain output curr ent limitation, reverse polarity protection as well as thermal shutdown in case of overtemperature. in order to avoid excessive power dissipation that coul d never be handled by the pass element and the package, the maximum output current is de creased at input voltages above v i =22v. the thermal shutdown circuit prevents the ic from i mmediate destruction under fault conditions (e.g. output continuously short-circuited) by switching off the power stage. after the chip has cooled down, the regulator restarts. this leads to an o scillatory behavior of the output voltage until the fault is removed. however, a junction temperature above 150 c is outside the maximum rating and therefore reduces the ic lifetime. the TLE4699 allows a negative supply voltage. however, se veral small currents are flowing into the ic increasing its junction temperature. th is has to be considered for the thermal des ign, respecting that the thermal protection circuit is not operating during reverse polarity condition. figure 4 block diagram volt age regulator circuit figure 5 output voltage vs. input voltage bandgap reference gnd q i b lockdiagram _v oltageregulator .vsd saturation control current limitation temperature shutdown c q load supply c i regulated output voltage i q i i v q + v i + v t diagram_output-inputvoltage.svg v q,nom v i v dr v q d v q d t i load c q d v q d t i q,max - i load c q v i(ext),min

data sheet 20 rev. 1.0, 2010-11-30 TLE4699 reset function 8 reset function 8.1 description reset function the reset function contains several features: output undervoltage reset: an output undervoltage condition is indi cated by setting the reset output ?ro? to ?low?. this signal might be used to reset a microcontroller during a low supply voltage condition. power-on reset delay time the power-on reset delay time t d,pwr-on allows a microcontroller and oscillator to start up. this delay time is the time period from exceeding the upper reset switching threshold v rt,hi until the reset is rele ased by switching the reset output ?ro? from ?low? to ?high?. the power-on reset delay time t d,pwr-on is defined by an external delay capacitor c d connected to pin ?d?, which is charged up by the delay capacitor charge current i d,ch starting from v d = 0 v. in case a power-on reset delay time t d,pwr-on different from the value for c d = 100nf is required, the delay capacitor?s value can be derived fr om the specified value given in item 8.2.15 : with ? t d,pwr-on : desired power-on reset delay time ? t d,pwr-on,100nf : power-on reset delay time specified in item 8.2.15 ? c d : delay capaci tor required the formula is valid for c d 10 nf.for a precise calculation consider also the delay capacitor?s tolerance. undervoltage reset delay time unlike the power-on reset delay time, the undervoltage reset delay t d time considers a short output undervoltage event, where the delay capacitor c d is assumed to be discharged to v d = v dst,lo only before the charging sequence starts. therefore, the undervoltage reset delay time t d is defined by the delay capacitor charge current i d,ch starting from v d = v dst,lo and the external delay capacitor c d . a delay capacitor c d for a different undervoltage reset delay time as specified in item 8.2.14 can be calculated similar as above: with ? t d : desired reset delay time ? t d,100nf : reset delay time specified in item 8.2.14 ? c d : delay capaci tor required the formula is valid for c d 10 nf.for a precise calculation consider also the delay capacitor?s tolerance. c d t d,pwr-on t d,pwr-on,100nf ------------------ ----------------- 100 nf = c d t d t d,100nf ---------------- 100 nf =
