Functional Description The TLE 4473 is a monolithic integrated voltage regulator with two very low-drop outputs, Q1 for loads up to 300 mA and Q2 providing a maximum of 180 mA. An input voltage in the range of 5.6 V VI 45 V is transformed to VQ2 = 5.0 V (2%) and VQ1 = 3.3 V 3% (TLE 4473 GV53) or VQ1 = 2.6 V 3% (TLE 4473 GV52). The device is also available with dual 5 V output voltage, please refer to the TLE 4473 GV55 data sheet. Two inhibit pins allow a flexible power management. Both outputs can independently be enabled or disabled. Thus the current consumption of the application can be reduced to a minimum. The quiescent current of the TLE 4473 with both outputs disabled is < 1 A. The TLE 4473 is designed to supply microprocessor systems and sensors under the severe conditions of automotive applications and is therefore equipped with additional protection functions against overload, short circuit and overtemperature. The device operates in the wide junction temperature range of -40 C to 150 C. Type TLE 4473 GV53 TLE 4473 GV52

The low drop regulator features a reset with adjustable power on delay for each of the outputs. In addition the output for the microcontroller supply comes up with a watchdog in order to supervise a microcontroller.

Reset and Watchdog Behaviour: The reset output RO1 is in high-state if the voltage on the delay capacitor CD1 is greater or equal VDL1. The delay capacitor CD1 is charged with the current IDC1 for output voltages greater than the reset threshold VRT1. If the output voltage drops below VRT1 ("reset condition"), the delay capacitor CD1 will be discharged rapidly. If VD1 reaches VDL1, the reset output RO1 is set to low. At power-on, the charging process of CD1 starts from 0 V, which leads to the equation
C D1 x V DU1 t D, on = ---------------------------I DC1
for the power-on reset delay time.
(1)
When the voltage at the delay capacitor has reached VDU1 and RO1 was set to high, the watchdog circuit is enabled and discharges CD1 with the constant current IDD1. If there is no rising edge observed at the watchdog input, CD1 will be discharged down to VDL1, where the reset output RO1 will be set to low and CD1 will be charged again with the current IDC1 until VD1 reaches VDU1 and reset will be set high again. If a watchdog pulse (rising edge at watchdog input WI) occurs during the discharge period, CD1 is charged again and the reset output stays high. After VD1 has reached VDU1, the periodical cycle starts again. The watchdog timing is shown in Figure 2. The maximum duration between two watchdog pulses corresponds to the minimum watchdog trigger time TWI,tr. Higher capacitances on pin D1 result in larger watchdog trigger time: T WI,tr = 0.42 ms/nF x C D1 (2)
max
If the output voltage Q2 decreases below VRT2 , the external capacitor CD2 is discharged. When the voltage at this capacitor drops below VDL2, a reset signal is generated at pin 11 (RO2), i.e. the reset output is set to low-level. If the output voltage rises above the reset threshold, CD2 will be charged with the constant current IDC2. After the power-onreset time, the voltage at the capacitor reaches VDU2 and the reset output will be set to high again. The value of the power-on-reset time can be set within a wide range depending of the capacitance of CD2 using Equation (1) analogous for Q2.
