Taiwan Semiconductor has expanded its portfolio of automotive Lighting ICs. The TSCR400 and TSCR402 are high side Constant Current Regulators (CCR) for linear LED driving and regulate with presets of 0.1mA and 20mA nominal (respectively) that are adjustable with an external resistor up to 65mA. Taiwan Semiconductor designed them to drive LEDs in strings and they reduce current at increasing temperatures to self-protect.
Typical applications are ambient light, interior light, turn signals, rear cluster lighting, reading light as well as instrument cluster illumination. Products and samples are orderable immediately from stock.
