Functional Description
The
TLE 4241 GM
is an integrated adjustable constant current source. It provides an
output current adjustable via different means (SET, PWM, reference resistor) which is
kept nearly independent from load and supply voltage changes. The IC is designed to
supply LEDs under the severe conditions of automotive applications resulting in constant
brightness and extended LED lifetime. It is provided in the very small P-DSO-8-9
(Micro 8) package. Protection circuits prevent damage to the device in case of overload,
short circuit, reverse polarity and overtemperature. The connected LEDs are protected
against reverse polarity as well as excess voltages up to 45 V. A status output allows
handling of open load and short circuit at the main output.
A PWM input offers the possibility to adjust the LED brightness by pulse width
modulation.
With an implemented high/low current switch the output current level can be reduced e.g.
for brake/tail light application.
The implemented features such as adjustable output current, the high/low current switch
and the provided PWM input make the device well suited for a broad range of LED and
other applications.
