Description Voltage Regulator
output voltage controlled comparing portion internal reference driving pass transistor accordingly. Saturation control function load current prevents oversaturation pass element. control loop stability depends output capacitor load current, chip temperature poles/zeros introduced integrated circuit. ensure stable operation, output capacitor's capacitance equivalent series resistor requirements given table "Operating Range" have maintained. details also typical performance graph "Output Capacitor Series Resistor ESRCQ Output Current IQ". Also, output capacitor shall sized buffer load transients. input capacitor needed control loop stability, recommended buffer line influences. Connect capacitors close terminals. Protection circuitry prevent well application from destruction case catastrophic events. These safeguards contain output current limitation, reverse polarity protection well thermal shutdown case overtemperature. order avoid excessive power dissipation that could never handled pass element package, maximum output current decreased input voltages above thermal shutdown circuit prevents from immediate destruction under fault conditions (e.g. output continuously short-circuited) switching power stage. After chip cooled down, regulator restarts. This leads oscillatory behavior output voltage until fault removed. However, junction temperatures above outside maximum ratings therefore reduce lifetime. TLE4675 allows negative supply voltage. However, several small currents flowing into increasing junction temperature. This considered thermal design, respecting that thermal protection circuit operating during reverse polarity condition.

Reset Function
Reset Function
Description Reset Function
reset function contains several features: Output Undervoltage Reset: output undervoltage condition indicated setting reset output "RO" "low". This signal might used reset microcontroller during supply voltage condition. Power-On Reset Delay Time power-on reset delay time td,PWR-ON allows microcontroller oscillator start This delay time time period from exceeding upper reset switching threshold VRT,hi until reset released switching reset output "RO" from "low" "high". power-on reset delay time td,PWR-ON defined external delay capacitor connected "D", which charged delay capacitor charge current ID,ch starting from case power-on reset delay time td,PWR-ON different from value 100nF required, delay capacitor's value derived from specified value given Item 7.2.15:
d,PWR-ON d,PWR-ON,100nF
with
td,PWR-ON: Desired power-on reset delay time td,PWR-ON,100nF: Power-on reset delay time specified Item 7.2.15 Delay capacitor required formula valid 10nF.For precise calculation consider also delay capacitor's tolerance.
Undervoltage Reset Delay Time Unlike power-on reset delay time, undervoltage reset delay time considers short output undervoltage event, where delay capacitor assumed discharged VDST,lo only before charging sequence starts. Therefore, undervoltage reset delay time defined delay capacitor charge current ID,ch starting from VDST,lo external delay capacitor delay capacitor different undervoltage reset delay time specified Item 7.2.14 calculated similar above:
d,100nF
with
Desired reset delay time td,100nF: Reset delay time specified Item 7.2.14 Delay capacitor required formula valid 10nF.For precise calculation consider also delay capacitor's tolerance.

Reset Function Reset Reaction Time case output voltage regulator drops below output undervoltage lower reset threshold VRT,lo, delay capacitor discharged rapidly. Once delay capacitor's voltage reached lower delay switching threshold VDST,lo, reset output will "low". Additionally delay capacitor discharge time trr,d internal time trr,int applies. Hence total reset reaction time trr,total becomes:
rr,total rr,int rr,d
with
trr,total: total reset reaction time trr,int: Internal reset reaction time; Item 7.2.16 trr,d: Delay capacitor discharge time. capacitor different from value specified Item 7.2.17,
typical performance graphs.
Reset Output Pull-Up Resistor RRO: Reset Output open collector output requiring external pull-up resistor voltage VIO, e.g. Item 7.2.7 minimum value external resistor given case connected applications, where external pull-up resistor connected different voltage rail than minimum pull-up resistor calculated minimum sink current capability given Item 7.2.6:
RO,low
with
RRO: Reset pull resistor VIO: Voltage rail, where pull resistor connected VRO,low: Maximum allowed voltage level logic "Low" signal inside application Please aware, that should exceed ratings given Item 4.1.3.
Reset Output "RO" case undervoltage reset condition reset output "RO" held "low" even input voltage This achieved supplying reset circuit from output capacitor.
