TLV4082DRYR

Comparators Overview

The TLV4082DRYR is a dual-channel, low-power analog comparator from Texas Instruments featuring an open-drain output topology. It operates within a supply voltage range of 1.5 V to 5.5 V and maintains a typical quiescent current of 2 µA. The device incorporates high-accuracy integrated reference thresholds with a precision hysteresis of 60 mV to reject input glitches. Designed for robust performance, it supports input voltages up to 5.5 V regardless of the supply rail and functions across a temperature range of -40°C to +125°C. The component is housed in a compact 6-pin µSON package.

Comparators Feature Summary

• Dual-channel architecture with integrated precision reference thresholds
• Open-drain output configuration allowing independent pull-up voltage selection
• Internal hysteresis mechanism ensures stable operation against input noise
• Fault-tolerant inputs maintain high impedance during power-off or ramp-up states

Comparators Applications

• Electricity meters
• Thermostats
• Cordless power tools
• Circuit breakers

Comparators Procurement Notes

Verify that the specific application circuit includes external pull-up resistors connected to the desired logic level, as the open-drain outputs require them to function correctly. Confirm that the supply voltage remains within the specified 1.5 V to 5.5 V range to ensure proper threshold accuracy and operational stability.

Comparators Selection Notes

Select this component when an open-drain interface is required to interface with different voltage domains than the comparator's supply rail. It is suitable for designs prioritizing low static current consumption and space efficiency. Ensure the design accounts for the necessary startup delay and propagation delays associated with the open-drain topology.

Comparators Part Context

This part belongs to the TLV40x2 family of micro-power comparators manufactured by Texas Instruments. It shares the same internal architecture and pinout as the push-pull variant, differing primarily in its output stage structure. The family is designed for portable and battery-operated applications requiring precise voltage monitoring.

Comparators FAQ

Can the TLV4082DRYR inputs withstand voltages higher than the supply voltage?

Yes, the inputs are fault-tolerant and can swing from ground to 5.5 V, even if no supply voltage is applied to the V+ pin.

Why are external resistors required for the TLV4082DRYR?

External pull-up resistors are mandatory because the device features open-drain outputs; without them, the outputs cannot drive high.
