SG2004J

Overview

The SG2004J is a dual high-side switch integrated circuit manufactured by Microchip Technology. It integrates two low RDS(ON) MOSFETs designed for controlling loads such as bulbs, LEDs, or DC motors in low-voltage environments. The device supports an operating voltage range of 6.0 V to 20 V, with an extended mode covering 4.0 V to 28 V. It features an 8.0 MHz 16-bit SPI interface for control and status reporting, including daisy-chain capability. Key electrical characteristics include a maximum on-resistance of 7.0 mΩ at 25 °C and a sleep current of less than 5.0 µA.

Feature Summary

• Dual high-side switching architecture with low on-resistance for efficient power control
• Integrated smart protection mechanisms including overcurrent shutdown, over-temperature protection, and auto-retry capabilities
• Programmable PWM module utilizing external clocks or internal oscillators with delay management
• Diagnostic features for open-load detection, short-to-battery sensing, and analog current feedback

Applications

• Low-voltage automotive lighting systems
• Factory automation load control
• Xenon module driving applications
• DC low voltage motor control

Procurement Notes

Verify the specific manufacturer origin, as the SG200 series was originally developed by Freescale Semiconductor prior to its acquisition by NXP. Confirm that the SG2004J variant aligns with the required pinout and electrical specifications for your design. Ensure compliance with RoHS directives if applicable to your project requirements before finalizing procurement.

Selection Notes

Select this component when a dual-channel high-side switch with integrated diagnostics is required. It is suitable for applications needing precise control over resistive or inductive loads within the specified voltage ranges. Consider the thermal performance and package constraints relative to the expected load currents and ambient operating temperatures.

Part Context

The SG200 series belongs to a family of devices designed for robust load switching in automotive and industrial sectors. While originally associated with Freescale Semiconductor, these components are now part of broader semiconductor portfolios. The SG2004J specifically offers dual-channel functionality, distinguishing it from single or quad-channel variants within the same family.

Replacement Considerations

Direct replacement availability depends on current supply chain allocations. Evaluate alternative dual high-side switches from manufacturers like NXP or STMicroelectronics that offer similar RDS(ON) values and SPI interfaces. Verify pin compatibility and thermal dissipation characteristics before substituting.
