TLV1852DGKR

Comparators Overview

The TLV1852DGKR is a dual-channel nanopower comparator from the Texas Instruments TLV185x family, housed in an 8-pin VSSOP package. It operates on a supply voltage range of 1.8V to 40V with a quiescent current of 750nA per channel for its push-pull output stage. The device features over-the-rail inputs capable of handling voltages up to 40V independent of the positive supply rail. It includes internal hysteresis and a power-on reset circuit to ensure known startup states.

Comparators Feature Summary

• Fail-safe input architecture maintains high impedance even when unpowered or below minimum supply voltage
• Over-the-rail common-mode operation allows input signals to exceed the positive supply rail up to 40V
• Integrated power-on reset ensures outputs remain in a defined state during system power-up sequences

Comparators Applications

• Voltage and temperature monitoring in low-power always-on systems
• Gas detector and smoke/heat detection circuits
• Motion detector applications
• Servo drive position sensing

Comparators Procurement Notes

Verify that the specific ordering suffix DGKR corresponds to the VSSOP-8 package variant. Confirm the device meets the required environmental operating conditions and electrical specifications for your application before finalizing procurement decisions.

Comparators Selection Notes

Select this component for designs requiring ultra-low power consumption alongside high-voltage tolerance. The push-pull output configuration eliminates the need for external pull-up resistors, simplifying board layout compared to open-drain alternatives while maintaining nanowatt standby currents.

Comparators Part Context

This part belongs to the TLV185x and TLV186x family of nanopower comparators designed for battery-operated and high-voltage monitoring applications. The TLV185x series specifically provides push-pull outputs, distinguishing it from the open-drain TLV186x series within the same functional family.

Comparators Replacement Considerations

The TLV1862DGKR serves as a parameter-equivalent alternative within the same family, differing primarily by offering an open-drain output stage instead of the push-pull configuration found in the TLV1852.
