Overview
The NSD5604NE-DHTSTR is a four-channel low-side driver IC from Novosense, integrating four NMOSFETs for driving resistive, capacitive, or inductive loads. It operates within an 8V to 50V supply range with a 55V breakdown voltage. Each channel supports over 500mA continuous current and up to 3.0A peak current. The device features configurable overcurrent protection via external resistors, integrated active clamping, and freewheeling diodes. It functions reliably across a temperature range of -40°C to 125°C.
Feature Summary
- Integrates four independent low-side NMOSFET channels capable of simultaneous conduction for high-load applications.
- Features configurable overcurrent protection points using external resistors, ensuring independent fault management per channel.
- Includes integrated active clamping and freewheeling diodes to support various current decay modes for inductive loads.
Applications
- Programmable Logic Controller (PLC) digital output modules
- Industrial automation and motion control systems
- High-voltage relay control in distributed I/O and DCS systems
Procurement Notes
Verify the specific suffix 'E' against the datasheet to confirm pinout and electrical characteristics match the required design specifications. Ensure the HTSSOP package variant aligns with the PCB footprint. Confirm that the operating voltage and thermal requirements are within the specified limits for the target application environment.
Selection Notes
Select this component when designing digital output stages requiring high current capacity and robust protection. It is suitable for replacing discrete MOSFET solutions to reduce board space and improve reliability. Consider the external resistor configuration for overcurrent thresholds and ensure adequate thermal management for parallel channel operation under heavy loads.
Part Context
This part belongs to the Novosense NSD5604 series of low-side drivers, designed for industrial control environments. It addresses the need for compact, high-performance digital output nodes in automation equipment. The series supports both single-channel and parallel configurations to meet varying load current demands in PLCs and motor control systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pinouts, voltage ratings, and thermal performance before substitution.
FAQ
How is the overcurrent protection threshold configured?
The overcurrent protection point for each channel can be configured independently using an external resistor connected to the chip.
What types of loads can the NSD5604NE drive?
It can drive resistive, capacitive, or inductive loads, supporting different current decay modes for inductive applications through its integrated active clamping and freewheeling diodes.
