NSD1624-DSPR

Gate Driver Overview

The NSD1624-DSPR is a high-voltage half-bridge gate driver designed for driving power MOSFETs or IGBTs. It provides a peak source current of 4A and a sink current of 6A. The device features an innovative isolation technology capable of withstanding over 700V DC voltage on the high-side section. It operates within a supply voltage range of 10V to 17V, with propagation delays less than 35ns and delay matching under 7ns. The SW pin offers high negative and dv/dt immunity up to 150V/ns. Input logic is compatible with TTL and CMOS standards.

Gate Driver Feature Summary

• High-voltage isolation capability supporting up to 700V DC on the high side
• Robust transient immunity at the SW pin against negative voltages and high dv/dt rates
• Integrated protection mechanisms including independent UVLO for both high and low sides
• Optimized switching performance characterized by low static current and minimal propagation delay

Gate Driver Applications

• Driving power MOSFETs in high-frequency switching circuits
• Driving IGBT modules in industrial power conversion systems
• Half-bridge configurations requiring high common-mode noise rejection
• Automotive power electronics and motor control applications

Gate Driver Procurement Notes

Verify that the specific suffix 'DSPR' corresponds to the SOP-8 package variant with 700V isolation rating, as other variants may offer different voltage levels. Confirm the manufacturer part number matches official NOVOSENSE documentation to ensure correct electrical characteristics. Check datasheet specifications for operating temperature ranges and input logic thresholds before integration. Ensure compliance with RoHS3 regulations if required by your application standards.

Gate Driver Selection Notes

Select this component when a half-bridge driver with high common-mode transient immunity is required. The 4A/6A output current capability suits medium-power MOSFET and IGBT applications. Consider the SOP-8 package constraints regarding thermal dissipation and pin spacing. Verify that the 10V-17V supply range aligns with your system's available power rails. Evaluate the need for integrated protections like UVLO and dead-time control against external circuit requirements.
