This device can also be used in safety systems, for detecting if the input voltage is too high or too low.

Working Principles

The BD45432G-TR Voltage Detector is based on CMOS technology. This device measures the input voltage, compares it to the set detection voltage, and then produces an output accordingly. This device has a hysteresis of 10mV, which guarantees an accurate and stable output even under severe noise conditions. When the input voltage exceeds the set detection voltage, the output is set to ON. When the input voltage falls below the set detection voltage, the output is set to OFF. This device can also be programmed to have a delayed output, when the detection voltage is exceeded. Finally, this device has an internal protection circuit, which prevents damage to the device when the input voltage is beyond the specified range.

Conclusion

The BD45432G-TR Voltage Detector is an ideal choice for PMIC - Supervisors applications. Featuring a high sinking output current, and consuming very little power, this device is very efficient and reliable. Furthermore, it is equipped with protection circuits, and is capable of working in extreme temperatures.
