L9822E中文资料八通道串行电磁阀驱动器数据手册ST规格书

描述 Description

The L9822E is an octal low-side solenoid driver realized in Multipower BCD technology particularly suited for driving lamps, relays and solenoids in automotive environment. The DMOS outputs L9822E has a very low power consumption.

Data is transmitted serially to the device using the Serial Peripheral Interface (SPI) protocol.

Status monitor function is available on all output lines.
