NCV7755DQR2G

Overview

The NCV7755DQR2G is an automotive-grade octal high-side driver featuring eight independent switches. It delivers up to 700mA per channel with a maximum supply voltage of 40V and operates within a junction temperature range of -40°C to +150°C. The device utilizes a 24-pin SSOP-EP package, providing integrated protection against overcurrent, short circuits, and thermal overload for reliable load management.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards
• Octal configuration with eight independent high-side switches
• Integrated diagnostic feedback for open-load detection
• Comprehensive protection including overcurrent and thermal shutdown

Applications

• Automotive lighting control systems
• Relay and solenoid driving in vehicle networks
• High-side load switching for accessory modules
• Body control module (BCM) output stages

Procurement Notes

Verify the specific suffix DQR2G confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the component meets AEC-Q100 Grade 1 requirements for your specific application environment. Cross-reference the exact part number with official onsemi documentation to confirm pinout compatibility and thermal pad specifications before finalizing procurement orders.

Selection Notes

Select this component when an automotive application requires multiple high-side outputs in a compact form factor. The integrated diagnostics simplify PCB layout by reducing external components needed for fault detection. Consider the 700mA per-channel limit when sizing loads, ensuring total power dissipation remains within the thermal constraints of the SSOP-EP package under worst-case operating conditions.

Part Context

This part belongs to onsemi's NCV series of automotive-grade power drivers, designed specifically for harsh environments. It complements other high-side switch solutions by offering higher channel density than single or dual drivers, making it suitable for complex body electronics where space optimization and robust fault handling are critical design priorities.

Replacement Considerations

Direct substitutes include the NCV7755DQAR2G variant, which shares identical electrical characteristics but may differ in reel quantity or specific manufacturing lot tracking. Verify that any alternative maintains the same SSOP-EP footprint and pin configuration to ensure mechanical compatibility without redesigning the host board.
