L6376D Description

The L6376D from STMicroelectronics is a high-performance 4-channel high-side power switch designed for general-purpose load driving applications. This surface-mount IC integrates N-channel MOSFETs in a 1:1 input-to-output ratio, supporting a wide load voltage range of 9.5V to 35V with a maximum output current of 500mA per channel. Unlike conventional switches, it operates without an external Vcc/Vdd supply, simplifying system design. Packaged in a PWRSO20 tube, the L6376D is RoHS3 compliant and meets REACH environmental standards, making it suitable for modern electronics requiring stringent regulatory compliance.

L6376D Features

• High-Side Configuration: Enables efficient load control with minimal external components.
• Integrated Protections: Includes fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO) for robust fault management.
• Status Flag: Provides real-time monitoring of switch operation, enhancing system diagnostics.
• Wide Voltage Range: Supports 9.5V–35V loads, ideal for industrial and automotive applications.
• No External Supply Needed: Eliminates the need for a separate Vcc/Vdd, reducing BOM complexity.
• 4 Independent Channels: Allows parallel or individual load control with 500mA current capability per channel.
• MSL 3 (168 Hours): Ensures reliability in humid environments during assembly and storage.

L6376D Applications

The L6376D excels in industrial automation, automotive systems, and power distribution networks where multi-channel high-side switching is critical. Key use cases include:

• Solenoid/Valve Control: Precise actuation in factory equipment or hydraulic systems.
• LED Driver Modules: Multi-string lighting with individual channel diagnostics.
• Relay/Actuator Management: Safe switching for motorized systems in automotive ECUs.
• Hot-Swap Circuits: Protects sensitive loads from inrush currents in server/telecom hardware.

Conclusion of L6376D

The L6376D stands out for its high integration, robust protections, and versatility in demanding environments. Its status flag feature, wide voltage range, and channel independence make it superior to basic load switches, while its compliance with RoHS3 and REACH ensures sustainability. Engineers designing multi-channel power systems will benefit from its simplified architecture and diagnostic capabilities, reducing development time and improving reliability. Ideal for industrial, automotive, and telecom applications, the L6376D delivers performance, safety, and efficiency in a compact package.
