TPCMP762-SO1R

Comparators Overview

The TPCMP762-SO1R is a dual-channel, low-power voltage comparator from the 3PEAK TPCMP76x series. It operates on a single supply of 2.5 V to 36 V or dual supplies of ±1.25 V to ±18 V. Key electrical parameters include a quiescent current of 150 μA per channel at 36 V, an input offset voltage of ±4.5 mV, and a typical high-to-low propagation delay of 300 ns with 100-mV overdrive. The device features an open-drain output capable of sinking up to 15 mA and supports inputs extending below ground. It is housed in an SOP-8 package and rated for operation between −40°C and +125°C.

Comparators Feature Summary

• Open-drain output configuration allows flexible logic level shifting and wired-AND functionality without internal ESD diodes between output and positive supply.
• Wide common-mode input range includes ground and extends slightly above the positive supply rail, enabling direct sensing at supply lines.
• Low power consumption design suitable for battery-operated applications while maintaining fast response times.
• Robust input protection and full fail-safe operation ensure stable performance under various signal conditions.

Comparators Applications

• Peak and zero-crossing detectors
• Threshold detectors and discriminators
• Logic level shifting or translation
• Window comparators
• IR receivers

Comparators Procurement Notes

Verify the specific ordering suffix SO1R corresponds to the SOP-8 package and tape-and-reel quantity of 4000 units as listed in the official order information table. Confirm that the MSL rating of 3 and green RoHS compliance meet your manufacturing requirements. Ensure the operating temperature range of −40°C to +125°C aligns with your system's thermal constraints before finalizing procurement.

Comparators Selection Notes

Select this component when a dual-channel comparator with wide supply voltage support (up to 36 V) and low quiescent current is required. The open-drain output is ideal for interfacing with different logic families or implementing bus structures. Consider the ±4.5 mV offset voltage and 300 ns propagation delay for precision timing applications. Verify that the SOP-8 package dimensions fit your PCB layout constraints.

Comparators Part Context

The TPCMP762-SO1R belongs to the TPCMP76x family of 36-V low-power comparators manufactured by 3PEAK. This series includes single-channel (TPCMP761) and quad-channel (TPCMP764) variants sharing similar electrical characteristics and pinout compatibility within their respective channel counts. The family is designed for general-purpose analog comparison tasks requiring high voltage tolerance and low power consumption.

Comparators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult 3PEAK directly for potential P2P replacements or verify compatibility with existing designs using alternative manufacturers' datasheets.

Comparators FAQ

Can the output voltage exceed the positive supply voltage?

Yes, there is no ESD diode between the output pins and the positive supply pin. The output can be pulled up to a voltage higher than the (+VS) pin, allowing logic high levels up to 36 V regardless of the supply voltage.

What is the maximum sink current capability of the open-drain output?

The output can sink up to 15 mA when the output voltage is 1.5 V. The low-level output voltage is specified as 250 mV max at 4 mA sink current.

Does the input common-mode range extend below ground?

Yes, the common-mode input voltage range includes ground. When operated from a single supply, the inputs can handle voltages down to the negative supply rail (−VS), which is typically 0 V.
