BD4LD650EFV-CE2

Power Distribution Switches, Load Drivers Overview

The BD4LD650EFV-CE2 is a four-channel low-side switch IC designed for automotive and industrial applications. It features an SPI interface for digital control and integrates load open detection, output ground fault detection, overcurrent protection, thermal shutdown, and active clamping. The device supports a supply voltage range of 3.0V to 5.5V and withstands up to 37V drain-source voltage. Typical on-resistance is 650mΩ with a maximum of 1500mΩ. It delivers 0.4A DC output current at 85°C ambient temperature and handles a single pulse energy of 125mJ at 25°C. The component is AEC-Q100 Grade A qualified and housed in a 20-HTSSOP-B package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the HTSSOP-B20 package dimensions align with the PCB footprint. Confirm AEC-Q100 Grade A qualification status if functional safety compliance is required for the target application environment.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a four-channel low-side switch with integrated diagnostics and SPI control is required. The 650mΩ typical on-resistance offers a balance between conduction loss and cost. The 37V drain-source voltage rating suits standard 12V automotive systems. Consider the 0.4A per channel limit at high temperatures when sizing for continuous loads.

Power Distribution Switches, Load Drivers Part Context

This part belongs to ROHM's Gen2 low-side switch family, optimized for automotive use. It replaces older generations by offering enhanced diagnostic features like ground fault detection and improved protection mechanisms. The SPI interface allows for flexible configuration and status reading, distinguishing it from parallel-input counterparts.

Power Distribution Switches, Load Drivers Replacement Considerations

Check for BD4LD650EFV-C as a potential variant, though suffixes may indicate packaging or specific automotive grade differences. Verify pin compatibility and electrical parameters before substituting with other 4-channel low-side switches from different manufacturers.
