NSV45015WT1G

Current Regulation/Management Overview

The NSV45015WT1G is a constant current regulator IC designed for LED applications, manufactured by onsemi. It operates within a supply voltage range of up to 45V and delivers a regulated output current of 15mA with an accuracy tolerance of ±20%. The device is housed in a compact SOD-123 surface-mount package, suitable for space-constrained designs. It supports both high-side and low-side sensing configurations, providing flexibility in circuit topology. The component is qualified to AEC-Q101 standards for automotive reliability and functions reliably across an extended temperature range from -55°C to +150°C.

Current Regulation/Management Feature Summary

• Utilizes self-biased transistor technology for stable current regulation similar to a constant current diode.
• Features negative temperature coefficient to prevent thermal runaway and protect LEDs under varying conditions.
• Capable of withstanding voltage surges common in automotive and industrial environments due to high voltage ratings.

Current Regulation/Management Applications

• Automotive LED lighting systems
• Industrial signage illumination
• Commercial display backlighting

Current Regulation/Management Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your assembly requirements. Confirm that the AEC-Q101 qualification aligns with your target application's reliability standards. Check the latest product change notifications regarding packaging materials or manufacturing site updates to ensure continuity of supply and compliance with environmental directives such as RoHS.

Current Regulation/Management Selection Notes

Select this component when a simple, robust solution for driving LEDs at a fixed current is required without complex control circuitry. The 15mA output is suitable for indicator LEDs or low-power signaling applications. Consider the ±20% tolerance if precise current matching is not critical. The wide operating temperature range makes it appropriate for harsh environments where standard commercial-grade components might fail.

Current Regulation/Management Part Context

This part belongs to the NSI45015 series of constant current regulators from onsemi. These devices are engineered to replace discrete resistor-based current limiting solutions, offering better stability against voltage fluctuations and temperature variations. The series is widely used in applications requiring reliable LED current management with minimal external component count.
