L9823013TR

L9823013TR Description

The L9823013TR from STMicroelectronics is an 8-channel low-side power driver IC designed for general-purpose switching applications. This obsolete but robust component integrates N-channel MOSFETs with an SPI interface, offering precise control over multiple loads. It operates within a 4.5V to 5.5V load voltage range, delivering up to 500mA per channel with a typical Rds(on) of 800mΩ, ensuring efficient power management. Packaged in a 24-pin SOIC and supplied in tape-and-reel (TR) format, it is suited for automated surface-mount assembly. Despite its obsolete status, it remains relevant for legacy designs due to its reliability and compliance with ROHS3 and REACH environmental standards.

L9823013TR Features

• 8-Channel Low-Side Driver: Independent control of up to 8 loads via SPI interface.
• Integrated Fault Protection: Includes open-load detection and over-temperature shutdown for enhanced system safety.
• Low Rds(on): 800mΩ typical reduces power dissipation, improving thermal performance.
• Wide Operating Voltage: Supports 4.5V–5.5V loads, ideal for 5V systems.
• Compact & Reliable: Surface-mount 24SO package with MSL1 (Unlimited) moisture sensitivity, ensuring long-term storage stability.
• SPI Interface: Enables daisy-chaining and scalable control in multi-device setups.

L9823013TR Applications

• Automotive Systems: ECU load driving, lighting control, and solenoid actuation in legacy vehicles.
• Industrial Automation: Multi-channel actuator or relay control in PLCs and motor drives.
• Consumer Electronics: Power distribution in printers, appliances, and LED arrays.
• Test Equipment: Multiplexed load switching for validation setups.

Conclusion of L9823013TR

While marked obsolete, the L9823013TR excels in multi-channel low-side driving with its low Rds(on), SPI programmability, and robust fault protection. Its 8-output configuration and 5V compatibility make it a pragmatic choice for legacy designs in automotive, industrial, and consumer applications. Engineers seeking a proven, RoHS-compliant solution for moderate-current switching will find this IC a cost-effective option despite its phase-out status.
