NSD5604-DHTSPR

Overview

The NSD5604-DHTSPR is a four-channel low-side driver IC from NOVOSENSE, integrating four NMOSFETs for driving resistive, capacitive, or inductive loads. It supports a wide operating voltage range of 8V to 50V with a 55V breakdown rating and features a typical on-resistance of 260mΩ. The device delivers a peak current of 3.0A per channel and includes an integrated LDO providing 5V at 20mA. Key protection mechanisms include configurable overcurrent protection via external resistors, undervoltage lockout, active clamping, and freewheeling diodes.

Feature Summary

• Integrates four independent low-side NMOSFET channels capable of simultaneous conduction
• Features configurable overcurrent protection points set by external resistors
• Includes integrated active clamping and freewheeling diodes for inductive load management
• Supports multiple current decay modes including slow decay and fast shutdown

Applications

• Industrial automation systems
• Digital machine tools
• General-purpose resistive, capacitive, and inductive load control

Procurement Notes

Verify the exact suffix against official NOVOSENSE documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required thermal performance and pin configuration for the target PCB layout. Cross-reference the datasheet revision date to validate feature availability and electrical characteristics before finalizing component selection.

Selection Notes

Select this component when designing circuits requiring multi-channel low-side switching with high surge current capabilities. The integrated LDO simplifies power supply design for logic interfaces. Consider the external resistor network for setting precise overcurrent thresholds to protect connected loads. Evaluate thermal dissipation requirements based on the 260mΩ on-resistance and expected duty cycles in industrial environments.
