TLV1812DSGR

Comparators Overview

The TLV1812DSGR is a dual-channel analog comparator from the Texas Instruments TLV181x family, housed in an 8-pin WSON package. It features rail-to-rail inputs and push-pull outputs. The device operates on a supply voltage range of 2.4 V to 40 V with a quiescent current of 5 µA per channel. Key electrical specifications include a typical propagation delay of 420 ns, an input offset voltage of 3 mV, and an input bias current of 0.15 pA. It supports an operating temperature range from -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input capability allows signal voltages to extend slightly beyond the supply rails without phase inversion.
• Integrated Power-On Reset (POR) ensures output remains in a known state during power-up and power-down sequences.
• Push-pull output stage provides both sourcing and sinking capabilities for driving loads such as LEDs or MOSFET gates.

Comparators Applications

• Appliances
• Factory automation and control
• Motor drives

Comparators Procurement Notes

Verify the specific ordering suffix 'DSGR' corresponds to the WSON-8 package and tape-and-reel quantity configuration. Confirm RoHS compliance status and functional safety documentation availability if required for system design. Ensure the selected variant matches the push-pull output requirement, distinct from the open-drain TLV182x series.

Comparators Selection Notes

Select this component when high-voltage operation up to 40 V is required alongside low power consumption. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-drain alternatives. Verify that the rail-to-rail input range meets the signal requirements and that the thermal performance of the WSON package suits the application's heat dissipation needs.

Comparators Part Context

This part belongs to the TLV181x/TLV182x family of micro-power comparators. The TLV181x sub-series specifically offers push-pull outputs, whereas the TLV182x offers open-drain options. All variants share common features including wide supply voltage support, low quiescent current, and integrated Power-On Reset functionality for reliable system startup.

Comparators Replacement Considerations

Check for alternate pinout versions like TLV1812DDFR or TLV1812PW if different packaging is needed. Ensure replacement parts maintain the push-pull output characteristic, as TLV182x devices have open-drain outputs which require external pull-up resistors.
