TS332IYQ3T

Overview

The TS332IYQ3T is a dual micropower low-voltage comparator from STMicroelectronics, designed for automotive and industrial applications. It operates within a supply voltage range of 1.6 V to 5.5 V with a typical quiescent current consumption of 20 μA per channel. The device features rail-to-rail inputs, allowing the common-mode input voltage to extend beyond the supply rails. Key electrical specifications include a propagation delay of 210 ns, an open-drain output configuration capable of sinking up to 22 mA, and an input offset voltage of 5 mV. It is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for robust reliability in vehicle environments.
• Rail-to-rail input capability enables accurate signal detection even when input voltages exceed the positive supply rail.
• Ultra-low power consumption of 20 μA supports battery-operated systems and energy-efficient designs.
• Open-drain output structure provides flexible interfacing with various logic families through external pull-up resistors.

Applications

• Automotive sensor signal conditioning and threshold detection
• Battery management system voltage monitoring
• Industrial process control limit switches
• Low-voltage portable electronic devices

Procurement Notes

Verify that the ordering suffix 'Q3T' corresponds to the specific tape-and-reel packaging and automotive grade designation required for your assembly line. Confirm the component meets AEC-Q100 requirements for your target application environment. Ensure the MiniSOP-8 package dimensions align with your PCB footprint design rules before finalizing procurement orders.

Selection Notes

Select this component when dual-channel comparison is needed in space-constrained automotive or industrial designs requiring low power. The rail-to-rail input feature is critical if input signals may swing near or slightly above the supply voltage. Compare against single-channel alternatives like TS331 if only one comparator is sufficient, or quad versions like TS334 for higher density needs.

Part Context

The TS332 belongs to the TS33x family of micropower comparators, which includes single (TS331), dual (TS332), and quad (TS334) variants. This family shares core architectural features such as low voltage operation and high ESD tolerance. The TS332IYQ3T specifically denotes the dual-channel version packaged in MiniSOP-8 with automotive qualification and reel packaging.

Replacement Considerations

Direct functional substitutes within the same family include TS331IST for single-channel needs and TS334IST for quad-channel configurations. Cross-family replacements require verification of pin compatibility and electrical parameter alignment, particularly regarding supply voltage ranges and output drive capabilities.
