ST intros energy saving voltage comparators

GENEVA, SWITZERLAND: STMicroelectronics has launched a general-purpose voltage comparator. It consumes one third the current for the same response time, compared with currently available devices such as the LMV331.

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 market’s widest operating voltage range, from 1.6V to 5V. This translates into greater design flexibility, enabling the integration of ST’s comparator in 1.8V, 3V and 5V systems.

ST’s latest voltage comparator delivers greater power efficiency and longer battery life in today’s portable electronics applications. 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.

It is 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.
