Description
The ALED1262ZT is a monolithic 12 output LED driver designed for automotive
exterior and interior lighting applications. The ALED1262ZT guarantees 19 V output
driving capability allowing users to connect several LEDs in series. In the output
stage, twelve regulated current sources provide from 6 mA to 60 mA constant current
to drive LEDs. The current is programmed by a single external resistor. In the
ALED1262ZT, LED open error detection is available.
The brightness can be adjusted separately for each channel through a 7-bit
grayscale control. A slow turn-on and turn-off time improves the system low noise
generation performance. Moreover the gradual output delay reduces the inrush
current. To further increase EMI performance, this device implements an internal
clock dithering to have a spread spectrum noise reduction.
Thermal management is equipped with overtemperature data alert and the output
thermal shutdown (170 °C). The I2C high clock frequency, up to 400 kHz, makes the
device suitable for high data rate transmissions. The supply voltage range is between
5.5 V and 38 V avoiding any external pre-regulation or additional load dump
protection on the power supply stage.
This device can operate in bus-driven mode (BDM) using I2C interface or in
standalone mode (SAM) using internal custom configuration by OTP.
