Innovations for safe system operation

Voltage detectors enable enhanced safe recovery in extra applications. STMicroelectronics STM1831 voltage detector has independent connections for the sense input and its own supply voltage.


STMicroelectronics has developed a new generation of innovative voltage detectors with extra features that enhance system safety and reliability for a wide variety of applications, the company said. The STM1831 voltage detector will be used in equipment such as autonomous systems and safety-related devices, enabling the electronics to recover safely if a voltage drop occurs in the power supply. Unlike other voltage monitors, the device has independent connections for the sense input and its own supply voltage. This allows the voltage detector to operate reliably even if the monitored voltage falls to 0 V.

A large selection of factory-trimmed voltage thresholds is available, from 1.6V to 5.7 V in 100 mV increments. This broad range allows designers to specify the exact voltage threshold they need to meet specific design requirements.

In addition, engineers can program the time delay between when the monitored voltage returns to normal and when the detector deactivates its alarm output. Only one external capacitor is needed to program the delay, which provides flexibility and simplifies design. The STM1831 also draws as little as 0.8uA typical supply current, allowing use in low-power applications such as battery-operated equipment.

Major features of the STM1831:

· ±2% voltage threshold accuracy

· Operating voltage 1.6V to 6.0V

· Open-drain output

· Power supply transient immunity

· Operating temperature range: -40 °C to +85 °C
