A17700LESBTR-DO

Overview

The A17700LESBTR-DO is a pressure sensor interface integrated circuit manufactured by Allegro MicroSystems. It features a serial interface and is designed for pressure sensor applications. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum input voltage of 5.5 V and a minimum of 4.5 V. It draws a typical operating supply current of 6 mA. The component supports analog output with a maximum output current of 30 mA. It is housed in a QFN-24 package and is rated for an operating temperature range from -40 °C to +150 °C.

Feature Summary

• Integrated signal conditioning for pressure sensors
• Serial communication interface capability
• High-temperature operation up to 150 °C

Applications

• Pressure sensing systems requiring high thermal stability
• Industrial sensor interfaces
• Automotive pressure monitoring applications

Procurement Notes

Verify the specific suffix 'DO' against official Allegro documentation to confirm pinout and functional differences from similar variants like 'AO'. Ensure compatibility with the target PCB footprint for the QFN-24 package. Confirm availability through authorized distributors as lead times may vary. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement.

Selection Notes

Select this component when a dedicated pressure sensor interface with serial output is required. The wide operating temperature range makes it suitable for harsh environments. Compare power consumption requirements against the 6 mA typical current draw. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating window. Consider the QFN-24 package size constraints during layout design.

Part Context

The A17700 series represents Allegro's solution for interfacing with pressure sensors. These ICs typically provide amplification, filtering, and digital conversion capabilities. The A17700LESBTR-DO variant is part of this family, focusing on robust performance in demanding conditions. It complements Allegro's broader portfolio of magnetic and current sensors.

Replacement Considerations

Check for direct substitutes within the A17700 family, such as A17700LESBTR-AO, ensuring pin compatibility. Verify if other Allegro sensor interfaces meet the same electrical specifications. Cross-reference with competitor parts only if they match the exact package and parameter set.
