MC22XSD200BEK

Overview

The MC22XSD200BEK is a dual high-side switch from the SG200 product family, manufactured by Freescale Semiconductor. It features two fully protected channels with low on-resistance and integrated control logic for industrial applications. The device supports up to 9.0 A steady-state current per channel and includes comprehensive protection mechanisms such as overcurrent, short-circuit, and overtemperature detection with programmable auto-retry functions. It operates within a voltage range of 8.0 V to 36 V in the normal operating range and extends to 6.0 V to 58 V in the extended range. Communication is handled via a 16-bit SPI port at rates up to 8.0 MHz.

Feature Summary

• Dual high-side switches with integrated diagnostic and protective functions
• Programmable auto-retry for overcurrent, short-circuit, and overtemperature events
• Open load detection capability in both off and on states
• Supports parallel output operation with improved switching synchronization

Applications

• Industrial 12 V and 24 V systems
• Halogen bulb control
• DC motor driving
• Low-voltage industrial lighting

Procurement Notes

Verify the exact suffix BEK against official datasheets to confirm package type and temperature grade. Ensure compatibility with 3.3 V or 5.0 V logic levels for SPI communication. Confirm supply voltage requirements align with the 8.0 V to 36 V normal operating range or 6.0 V to 58 V extended range specifications.

Selection Notes

Select this component for applications requiring robust high-side switching with detailed fault diagnostics. Consider the 9.0 A current capacity and low RDS(on) for efficient power handling. Evaluate the need for PWM clock programming and open load detection features specific to LED or bulb loads.

Part Context

This part belongs to the SG200 family of high-side switches designed for industrial environments. It integrates control logic and protection features typically found in discrete solutions, simplifying board design. The family offers various configurations including triple and quad switches with different resistance values.

Replacement Considerations

Check for direct substitutes within the SG200 family, such as single or triple channel variants, depending on pinout compatibility. Verify that alternative devices support the required SPI interface speed and voltage ranges.
