BTS722204ESAXUMA1

Overview

The BTS72220-4ESA is a SPOC+2 multichannel SPI smart high-side switch in a PG-TSDSO-24 package. It features four N-channel outputs with current ratings of 7 A and 4 A, and on-resistances up to 22 mΩ. The device operates within a supply voltage range of 6 V to 18 V and supports PWM input. It includes integrated protection against short circuits, overloads, and overtemperature, along with diagnostic status flags.

Feature Summary

• Multichannel SPI control interface for intelligent load switching
• Integrated diagnostic status flags and fault protection mechanisms
• Configurable PWM input capability for dynamic load control

Applications

• Body Control Modules
• Fuse Box systems
• Junction Box applications
• Lighting control
• Motor Control & Drives

Procurement Notes

Verify the specific suffix 'XUMA1' to confirm tape-and-reel packaging configuration. Ensure compatibility with the required SPI communication protocol and voltage levels. Confirm automotive qualification status matches project requirements. Check lead times as manufacturing cycles may vary. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component for applications requiring multiple high-side switches with centralized digital control. The SPOC+2 architecture reduces board space compared to discrete solutions. Consider thermal management due to high current capabilities. Verify that the TSDSO-24 package fits the PCB layout constraints. Evaluate the need for integrated diagnostics versus external monitoring.

Part Context

This part belongs to Infineon's SPOC+2 family, designed for automotive power distribution. It integrates multiple high-side switches into a single controller unit. The series targets body electronics and lighting applications where space efficiency and intelligent control are critical. It replaces traditional relay-based or discrete switch implementations.

Replacement Considerations

Check for direct substitutes within the BTS72220 series with different suffixes indicating packaging variations. Verify pin-to-pin compatibility if replacing with other SPOC+2 variants. Ensure electrical parameters match the original design requirements.
