STMicroelectronics Multiplexer 8 Octal 20-Pin SOIC L9822EPD013TR

STMicroelectronics L9822EPD013TR Multiplexer 8 Octal 20-Pin SOIC is an advanced low-side solenoid driver implemented with Multipower BCD technology. Engineered for automotive and industrial applications, it drives lamps, relays, and solenoids with high efficiency and reliability.

The device incorporates eight low RDSon DMOS outputs, each with an internal 36 V clamp to prevent voltage spikes. These outputs provide a maximum on-state resistance of 1 Ω, ensuring minimal power loss during operation. The L9822E supports serial data communication via an 8-bit SPI protocol, enabling precise control and diagnostic feedback on overload and open circuit conditions.

Designed to operate across a broad temperature range of -40°C to 150°C, this multiplexer IC is suited for harsh environments often encountered in automotive electronics. Its low quiescent current of 10 mA minimizes energy consumption during standby, enhancing overall system efficiency.

Package options include PowerSO-20 and Multiwatt 15, both surface mount designs facilitating compact PCB layouts. The device's cascadable design allows multiple units to be connected for controlling larger arrays of solenoids or relays, suitable for complex automotive or industrial control systems.

Typical use cases include automotive lamp control, relay driving, solenoid actuation and other applications requiring robust low-side driver ICs. Its integrated protection features such as output short circuit protection contribute to resilience and longer operational life.
