Functional Description  
The TLE4309 is an integrated adjustable constant current source for driving loads up to  
500 mA. The output current level can be adjusted with an external shunt resistor.  
Supplying high power LEDs with the TLE4309 ensures constant brightness independent  
from supply voltage or LED forward voltage spread. Therefore, LED lifetime is extended  
by protecting from overcurrent and overtemperature  
The PWM/EN input permits LED brightness regulation by pulse width modulation.  
Setting the pin to “low” switches off the IC entirely. Due to the high impedance of the  
PWM/EN input, the TLE4309 can be used as a protected high side switch.  
Protection circuits prevent from damage to the IC in case of overload, short circuit, and  
reverse polarity. A chip temperature monitoring circuit shuts off the power stage and  
prevents the IC from destruction under fault conditions.  
In case of negative input voltage, a leakage current is flowing only from the output to the  
input, hence the LED are protected against reverse supply. Input voltage peaks up to  
45 V are absorbed by the IC, preventing the LEDs from overcurrent.  
The TLE4309G is provided in the surface mounted PG-TO-263 package with excellent  
thermal resistance.
