TIOS102YAHR

Sensor And Detector Interfaces Overview

The TIOS102YAHR is a digital sensor output driver from Texas Instruments housed in a 12-pin DSBGA package (2.45 mm x 1.7 mm). It operates on a supply voltage range of 4.75 V to 36 V with a typical quiescent current of 1.5 mA when disabled. The device features configurable high-side, low-side, or push-pull outputs and includes an integrated linear regulator for logic supply. It supports IEC 61000-4-5 surge protection up to ±1.2 kV and reverse polarity protection up to 65 V. The operating temperature range extends from -40°C to +125°C.

Sensor And Detector Interfaces Feature Summary

• Configurable output topology supporting high-side, low-side, and push-pull modes via pin programming.
• Integrated EMC protection handling IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge events.
• Active reverse polarity protection across VCC, OUT, and GND pins up to 65 V.
• External resistor-configurable current limiting with fault indication and auto-recovery capabilities.

Sensor And Detector Interfaces Applications

• Proximity switches
• Capacitive and inductive sensors
• Actuators
• Digital outputs

Sensor And Detector Interfaces Procurement Notes

Verify the ordering suffix YAH corresponds to the 12-pin DSBGA package configuration. Confirm that the specific variant matches the required LDO presence or absence, as the base TIOS102 model lacks an internal regulator while other family members include it. Ensure the component meets functional safety documentation requirements if applicable to the system design.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring robust industrial sensor interfacing with integrated transient protection. The small DSBGA footprint suits space-constrained designs. Verify the need for an internal LDO; if logic power regulation is required, consider variants like TIOS1023L which offer selectable LDO outputs via the VSEL pin in the same package.

Sensor And Detector Interfaces Part Context

The TIOS102YAHR belongs to the TIOS102 family of digital sensor output drivers designed for industrial automation. It serves as a pin-compatible upgrade to the TIOS101 series, offering improved thermal performance and lower residual voltage. The device integrates diagnostic features such as overcurrent, overtemperature, and undervoltage lockout reporting through the NFAULT pin.

Sensor And Detector Interfaces Replacement Considerations

TIOS101DMWR is a pin-compatible predecessor with similar functionality but different electrical characteristics. TIOS1023L is an alternative within the same package that includes a configurable LDO. Verify thermal resistance values and LDO requirements before substitution.
