Features

• Output voltage tolerance ≤ ±2%  200 mA output current capability  Low-drop voltage  Very low standby current consumption  Overtemperature protection  Reverse polarity protection  Short-circuit proof  Adjustable reset threshold  Watchdog  Wide temperature range  Suitable for use in automotive electronics  Green Product (RoHS compliant)  AEC Qualified Functional Description TLE 4263 is a 5-V low drop voltage regulator in a SMD package PG-DSO-14, PG-DSO -20, or PG-DSO-8. The maximum input voltage is 45 V. The maximum output current is more than 200 mA. The IC is short-circuit proof and incorporates temperature protection which turns off the IC at overtemperature. The IC regulates an input voltage VI in the range of 6 V < VI < 45 V to VQ,nom = 5.0 V. A reset signal is generated for an output voltage of VQ,rt < 4.5 V. This voltage threshold can be decreased to 3.5 V by external connection of a voltage divider. The reset delay can be set externally by a capacitor. The integrated watchdog logic supervises the connected micr ocontroller. The IC can be switched off via the inhibit input, which causes the current consumption to drop from 900 μA to typical 0 μA.

Data Sheet 2 Rev. 2.9, 2013-11-25 TLE 4263 Choosing External Components The input capacitor CI is necessary for compensation of line influences. Using a resistor of approx. 1 Ω in series with CI, the oscillating circuit consisting of input inductivity and input capacitance can be damped. The output capacitor is necessary for the stability of the regulating circuit. Stability is guaranteed at values ≥ 22 μF and an ESR of ≤ 3 Ω within the operating temperature range. For small tolerances of the reset delay the spread of the capacitance of the delay capac itor and its temperature coefficient should be noted.

Data Sheet 4 Rev. 2.9, 2013-11-25 TLE 4263 Circuit Description The control amplifier compares a reference voltage, which is kept highly accurate by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any over-saturation of the power element. If the externally scaled down output voltage at the reset threshold input drops below 1.35 V, the external reset delay capacitor is discharged by the reset gener ator. When the voltage of the capacitor reaches the lower threshold VDRL, a reset signal occurs at the reset output and is held until the upper threshold VDU is exceeded. If the reset threshold input is connected to GND, reset is triggered at an output voltage of typ. 4.65 V. A connected microcontroller will be monitored through the watchdog logic. In case of missing pulses at pin W, the reset output is set to low. The pulse sequence time can be set in a wide range with the reset delay capacitor. The IC can be switched at the TTL-compatible, low-active inhibit input. The IC also incorporates a number of internal circuits for protection against:  Overload  Overtemperature  Reverse polarity Figure 2 Block Diagram Input AEB03068 INH GND Output D RO RADJ Reset Delay Reset Output Reset Threshold Watchdog W Temperature Sensor Generator ResetReference Bandgap Adjustment Buffer Control Amplifier Saturation Control and Protection Circuit Inhibit Ι Q GND

Data Sheet 10 Rev. 2.9, 2013-11-25 TLE 4263 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 = (trd × ID,ch)/ΔV (1) Definitions:  CD = delay capacitor  trd = reset delay time  ID,ch = charge current, typical 60 μA  ΔV = VDU, typical 1.70 V  VDU = upper delay switching threshold at CD for reset delay time Figure 5 Time Response, Watchdog with High-Frequency Clock AET03066 IV VQ Q, rtV VD DUV VDRL ROV rdt trr < rrt Vd td = D, chI DC Power-ON Reset Over- temperature at Input Voltage Drop Under- voltage Spike Secondary Bounce Load t t t t

Data Sheet 11 Rev. 2.9, 2013-11-25 Reset Switching Threshold The present default value is ty p. 4.65 V. When using the TLE 4263 the reset threshold can be set to 3.5 V < VQ,rt < 4.6 V by connecting an external voltage divider to pin RADJ. The calculation can be easily done since the reset adjust input current can be neglected. If this feature is not needed, the pin has to be connected to GND. VQ,rt = (1 + R1/R2) × VRADJ,th (2) Definitions:  VQ,rt = reset threshold  VRADJ,th = comparator reference voltage, typical 1.35 V Watchdog Timing The frequency of the watchdog pulses has to be higher than the minimum pulse sequence which is set by the external reset delay capacitor CD.
