Description

General part information

BD18354MUF-M Series

BD18354MUF-M is a 2ch Constant-Current and Voltage Controller. High side current detection amplifier is built in. PWM dimming duty can be freely set with built-in PWM generation circuit. PWM dimming realizes by driving an external P-ch FET. The BD18354MUF-M can support individual 10-bit analog dimming and 10-bit PWM dimming for LED current by programing the 10-bit register via SPI. BD18354MUF-M can be started up by reading data from the EEPROM by setting the MODE pin without SPI communication. The BD18354MUF-M will support LIMP-HOME mode and STAND-ALONE mode if SPI communication has an error. In the LIMP-HOME mode, it operates by loading the register settings stored in the connected EEPROM. In the STAND-ALONE mode, individual LED current can be set by the external pins and can keep LED current sourcing during applying input power without SPI communication.
