Product Overview
BD18397EUV-ME2 is an automotive 2-channel, synchronous buck DC/DC LED driver with using on-time topology supporting near fixed switching frequency and fast switching duty regulation and with using average LED current feed buck topology for more accreted LED current regulation system over wide input, LED output range. It can support individual 10-bit analogue dimming and 10-bit PWM dimming for LED current by programming the 10-bit register via SPI. It will support LIMP-HOME mode, if SPI communication has an error. In the LIMP-HOME mode, individual LED current can be set by the external pins and can keep LED current sourcing during applying input power without SPI communication. Applications include automotive exterior lamps rear, turn, DRL/position, fog, high/low beam etc.
- ISO 26262 process compliant to support ASIL-B, on-time topology for near fixed frequency switching
- Average LED current regulation, protection diodes less for current sense pins
- Cycle-by-cycle switch over current protection, thermal shutdown (TSD)
- Thermal sensor reading, serial peripheral interface (SPI), LIMP-HOME mode
- 5V to 45V VIN continuous input voltage range
- 2.5V to 60V LED output voltage range
- Programmable switching frequency range from 200KHz to 2.25MHz
- 10-bit analogue dimming range from 5% to 100%
- AEC-Q100 grade 1 qualified
- Operating temperature range from -40°C to +150°C, HTSSOP-C48 package
