TLV1862DGKR

Comparators Overview

The TLV1862DGKR is a dual-channel nanopower analog comparator from the Texas Instruments TLV185x/TLV186x family. It operates on a supply voltage range of 1.8V to 40V with a quiescent current of 440nA per channel in open-drain configuration. The device features over-the-rail inputs capable of handling common-mode voltages up to 40V independent of the supply rail, and includes an internal power-on reset circuit for known startup states. It utilizes an open-drain output stage and is housed in an 8-pin VSSOP package.

Comparators Feature Summary

• Over-the-rail input capability allowing operation up to 40V regardless of supply voltage
• Fail-safe high-impedance inputs that prevent false triggering during power loss
• Internal power-on reset ensures outputs remain in a defined state until minimum supply voltage is reached
• Open-drain output stage suitable for level translation applications

Comparators Applications

• Voltage monitoring in low-power always-on systems
• Temperature sensing circuits
• Gas detector instrumentation
• Smoke and heat detection systems

Comparators Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging format. Confirm the component meets RoHS compliance standards for your region. Ensure the design accommodates the thermal characteristics associated with the VSSOP-8 package under maximum operating temperature conditions.

Comparators Selection Notes

Select this model when an open-drain output is required for level shifting or wired-OR logic configurations. Choose this part over the push-pull variant if external pull-up resistors are preferred or necessary for interfacing with different logic families. Consider the wide supply range for battery-powered applications requiring long operational life.

Comparators Part Context

This component belongs to the TLV185x and TLV186x family of nanopower comparators designed for high-voltage, low-power environments. While the TLV185x series provides push-pull outputs, the TLV186x series specifically offers open-drain outputs. Both share identical input stages and fail-safe capabilities within the same package options.

Comparators Replacement Considerations

The TLV1852DGKR serves as a functional substitute within the same family, differing only by its push-pull output stage instead of open-drain.
