It also has wide applications in landline communication systems and computer-based data acquisition and control systems. The comparator is used for various security applications for monitoring, controlling, and detecting any unauthorized access or tampering of sensitive systems.

Working Principle

The MIC6270BM5-TR 3-terminal precision voltage comparator operates on the basic principle of differential voltage comparison. It has two input pins – inverting (-) and non-inverting (+) – and one output pin. The output pin is connected to the inverting pin internally via a resistive feedback loop and is used to determine if the voltage at the non-inverting input is higher or lower than the voltage at the inverting input. When the voltage at the non-inverting input is higher, the output pin is driven high, indicating a positive comparison, and when the voltage at the inverting input is higher, the output pin is driven low, indicating a negative comparison.

The MIC6270BM5-TR comparator is designed with an internal voltage reference that automatically adjusts to detect input voltages as low as 0.75V and as high as 4.50V. It has a power supply range of 1.8V to 5.5V and can provide quick response to input signals. The input current of the comparator is maintained constant even under extreme conditions thus indicating good thermal performance.

The MIC6270BM5-TR comparator offers low static power consumption and low power output and input thresholds. Its low power consumption feature provides a significant benefit in applications where the power supply is sensitive. Furthermore, the MIC6270BM5-TR comparator shows a hysteresis range voltage of ±75mV and is equipped with an open drain output stage with TTL interface for direct interfacing with MCUs and logic circuitry.

The MIC6270BM5-TR comparator also has protection from reverse voltage and over-voltage faults. It is RoHS-compliant and is immune to ESD. This precision voltage comparator also supports a wide temperature range operation and is available in various packages.

In conclusion, the MIC6270BM5-TR comparator from the Linear-Comparator series offers high precision, improved linearity and low-power consumption applications. It is suitable for a variety of field applications that require differential voltage comparison.
