3 Description
The TPS92621-Q1 single-channel LED driver
includes a unique thermal management design
to reduce temperature rising on the device. The
TPS92621-Q1 is a linear driver directly powered by
automotive batteries with large voltage variations to
output full current loads up to 300 mA. Shunt resistor
is leveraged to share output current and dissipate
power out of the driver. The device full-diagnostic
capabilities include LED open, LED short-to-GND
circuit, and device overtemperature protection.
The one-fails-all-fail feature of TPS92621-Q1 can
work together with other LED drivers, such as
the TPS9261x-Q1, TPS9262x-Q1, TPS9263x-Q1,
and TPS92830-Q1 devices, to address different
requirements.
