General Description

BD5LL20AEFV-C is 5-channel SPI-input low side switch

developed as engine control. It has built-in open load

detection function, over current protection function,

thermal shutdown function, and active clamp function. It

also has a 5 V output LDO as a power supply for the

microcontroller and a built-in K-LINE communication

circuit, making it suitable for motorcycle engine control.
