Japan-based Rohm Semiconductor said on Feb. 14 that it has successfully developed a 4-channel LED driver IC –BD183x7EFV-M – applicable for automotive parts such as brake lights, fog lamps and turn signals. It is also embedded with MOSFET.
The product raised efficiency by reducing the number of heat dispersion circuits to just 1. Previously, a circuit was required per number of channels. In the BD183x7EFV-M, the 4 channels are provided in a tiny 16Pin package.
The product also supports individual LED control, so that a single LED driver is necessary for igniting automotive LED lamps of different specs.
The BD183x7EFV-M targets mostly emerging markets such as India, and satisfies the standards for global 2-wheel vehicle license plates. Mass production began in December, 2019 to the tune of 250,000 per a month. The samples cost 500 yen each.
