The ultra-low power device achieves a propagation delay of 200ns while consuming only 30µA of supply current, which is 66% lower than other solutions in the market. This energy efficiency allows clients to design products that use less power and have less impact on the environment.

The comparator delivers a stable response time over a wide temperature range, from -40°C to 125°C, and offers superior ESD (Electrostatic Discharge Protection) capabilities. It integrates an open-drain output and rail-to-rail inputs with the widest operating voltage range, from 1.6V to 5V. This translates into greater design flexibility, enabling the integration of the comparator in 1.8V, 3V and 5V systems.

Available in single, dual and quad versions in space-saving SMD packages, ST's ultra-low-power general-purpose voltage comparator targets signal-conditioning applications in mobile communications, battery-operated portable electronics, and alarm and security systems.

The TS33 general-purpose voltage comparator is now sampling. Unit pricing in quantities of 1,000 pieces starts at $0.28 (TS331—single), $0.35 (TS332—dual) and $0.39 (TS334—quad).
