STMicroelectronics (STM) has introduced a general-purpose voltage comparator that is said to consume one third the current for the same response time, compared with currently available devices such as the LMV331.
ST’s latest voltage comparator is supposed to address the demand for greater power efficiency and longer battery life in today’s portable electronics applications, in keeping with the Company’s ongoing commitment to sustainability. 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.
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.
