TIOS1023LYAHR

Sensor And Detector Interfaces Overview

The TIOS1023LYAHR is a digital sensor output driver from Texas Instruments housed in a 12-pin DSBGA package. 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 an integrated 3.3-V linear regulator capable of delivering up to 20 mA. It supports configurable PNP, NPN, or push-pull outputs and includes active reverse polarity protection up to 65 V. Integrated EMC protection provides ±8 kV IEC 61000-4-2 ESD, ±4 kV EFT, and ±1.2 kV surge tolerance. The operating temperature range extends from -40°C to +125°C.

Sensor And Detector Interfaces Feature Summary

• Configurable high-side, low-side, or push-pull driver output
• Integrated 3.3-V LDO for local controller power supply
• Robust EMC protection against surge, EFT, and ESD transients
• Active reverse polarity protection on supply and output pins

Sensor And Detector Interfaces Applications

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

Sensor And Detector Interfaces Procurement Notes

Verify the specific YAH suffix indicates the 12-pin DSBGA package configuration. Confirm the internal LDO is fixed at 3.3 V as specified for the TIOS1023 variant. Ensure the ordering part number matches the exact pinout and thermal pad requirements for the target PCB layout.

Sensor And Detector Interfaces Selection Notes

Select this component when a compact solution is required for industrial sensor interfaces. The integrated LDO simplifies power distribution by providing a stable logic supply. Verify that the external RSET resistor correctly sets the desired current limit between 35 mA and 300 mA based on load requirements.

Sensor And Detector Interfaces Part Context

This device belongs to the TIOS102x family of digital sensor output drivers. It serves as an upgraded replacement for the TIOS101 series, offering improved thermal performance and lower residual voltage. The family shares similar functional block diagrams but varies in package options and integrated regulator voltages.

Sensor And Detector Interfaces Replacement Considerations

TIOS101 is a pin-compatible predecessor with different electrical characteristics. TIOS1023L offers selectable LDO voltage via the VSEL pin. TIOS1025 provides a 5-V LDO option instead of 3.3 V.
