Energy-Saving Voltage Comparators from STMicroelectronics Boast Industry's Lowest Current Consumption
Power-stingy integrated circuits help increase efficiency in portable electronics
Geneva, - STMicroelectronics (NYSE:STM), a global semiconductor leader serving customers across the spectrum of electronics applications and a leading manufacturer of multi-segment ICs, today introduced a general-purpose voltage comparator that consumes one third the current for the same response time, compared with currently available devices such as the LMV331.
ST's latest voltage comparator addresses 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. This unmatched energy efficiency allows ST customers 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 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.
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 sampling now and ready to start volume production. Unit pricing in quantities of 1,000 pieces starts at $0.28 (TS331 - single), $0.35 (TS332 - dual) and $0.39 (TS334 - quad).
