Comparators

The TS3121 and TS3121A are advanced rail-to-rail, open-drain comparators designed for high-speed response with low power consumption and come in a compact size, making them ideal for space-constrained applications.

These comparators feature a low offset voltage of 2 mV max at 25 °C (A-grade), low power consumption of 70 μA typical while offering a fast propagation delay of 60 ns, and a guaranteed start-up time.

Suitable for industrial and automotive applications, power tools, overcurrent protection, controllers and sensors, they operate over a wide supply voltage range (1.7 to 5.5 V) and temperature range (-40 °C to +125 °C).

Increased integration of device functionality for autonomous driving, in-vehicle-networking, infotainment and sensor integration are key drivers for reduced package sizes in automotive applications.
To facilitate design in space constraint applications, ST introduces its best-seller comparator TS3011IYCT in a tiny SC-70 package (2.0 x 2.1 mm).

The TSX393 and TSX3702 micropower 16 V dual CMOS voltage comparators and the TSX339 and TSX3704
micropower 16 V quad CMOS voltage comparators exhibit a very low current consumption of 5 µA (typical) per comparator.
The TSX comparators  help save energy in application that use power-saving design techniques reducing by a factor 3 the current consumption of equivalent existing devices.

The TSX comparators also increase reliability with improved robustness (ESD tolerance 4 Kv HBM).
