NCV84160DR2G

Overview

The NCV84160DR2G is a self-protected high-side power switch IC from onsemi, designed for automotive and industrial applications. It features a single output with an output current of 1 A and a maximum current limit of 12 A. The device has a maximum on-resistance of 320 mOhms and operates within a supply voltage range of 4.5 V to 28 V. It supports fast switching with a maximum turn-on time of 10 us and a maximum turn-off time of 10 us. The component is qualified to AEC-Q101 standards and functions reliably across a temperature range of -40 C to +150 C. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates advanced protection mechanisms including overvoltage active clamping, active surge current management, and automatic restart thermal shutdown.
• Provides proportional load current sensing via the CS pin, which can be disabled using the CS_DIS pin for specific control requirements.
• Features dedicated detection capabilities for VD output short circuits and open-load conditions when the device is turned off.

Applications

• Switching resistive loads in automotive systems
• Controlling inductive loads such as solenoids and relays
• Managing capacitive loads with integrated surge protection

Procurement Notes

Verify that the specific part number matches the required AEC-Q101 qualification level for your application environment. Confirm that the SOIC-8 package dimensions align with your PCB footprint design constraints. Ensure that the operating voltage range of 4.5 V to 28 V is compatible with your system's power supply specifications before finalizing procurement.

Selection Notes

Select this component when a single-channel high-side switch with integrated self-protection is required. It is suitable for designs needing precise current sensing and robust fault handling in harsh environments. Consider the 320 mOhms on-resistance for power dissipation calculations and ensure the 1 A continuous output current meets the load requirements without exceeding thermal limits.

Part Context

This device belongs to the NCV84160 series of smart power switches manufactured by onsemi. It is specifically engineered for high-reliability applications where compact size and comprehensive protection are critical. The series targets markets requiring compliance with stringent automotive quality standards while offering simplified design through integrated driver and protection circuitry.

Replacement Considerations

The NCV84160DR2G may serve as a direct replacement for other single-channel high-side switches within the same family or similar functional equivalents, provided the electrical parameters and pinout compatibility are verified against the target application requirements.

FAQ

How is the current sensing function managed?

The device provides proportional load current sensing at the CS pin. This feature can be disabled by connecting the CS_DIS pin to ground via a pull-down resistor or leaving it floating, depending on the desired configuration.

What protection features are included for inductive loads?

The NCV84160 includes an integrated clamp specifically designed for inductive switching applications, along with active surge current management to protect the device during load transitions.
