The iND83209 can be connected directly to the automotive supply and withstand up to 45V load dump from a car battery. The integrated power management unit implements two on-chip voltage regulators with only one requiring an external capacitor.
The 3x LED drivers can each support a maximum of 60mA constant current with a 100uA resolution at high-voltage (up to VBAT). An integrated temperature sensor ensures the chip does not exceed its operating range of -40°C to +125°C. There are two LIN transceivers and controllers (master and slave, version 2.2) that provide LIN auto addressing functionality by using the LIN Switch Method (LSM). The device also features an integrated 10-bit ADC for monitoring purposes.
The iND83209 integrates six GPIOs that enhance its functionality and flexibility, making the device suitable for general purpose microcontroller applications. For lighting applications, the device can be expanded to drive additional RGB LEDs by using external MUX switches to time multiplex drive currents.
Evaluation kits are available to enable rapid development and testing of advanced lighting prototypes.
