LT6700HVIS6-1#TRPBF

Overview

The LT6700HVIS6-1#TRPBF is a micropower, low voltage dual comparator with an internal 400mV reference. It operates on supplies from 1.4V to 18V and draws 17µA typical supply current at 5V. The device features open-collector outputs capable of sinking up to 40mA, allowing level translation to voltages up to 36V for the HV variant. Input bias current is typically ±10nA. Propagation delay is specified at 29µs maximum for low-to-high transitions. It is housed in a 6-lead TSOT-23 package.

Feature Summary

• Integrates two comparators with a fixed 400mV internal reference
• Supports over-the-top input operation up to 36V independent of supply
• Includes internal hysteresis for stable output switching
• Open-collector outputs enable flexible level translation

Applications

• Battery-powered system monitoring
• Threshold detectors
• Window comparators
• Relay driving
• Automotive monitor and controls

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging. Confirm the 'HV' designation matches the required 36V input/output rating versus standard 18V limits. Ensure the 'I' grade meets the -40°C to 85°C operating temperature range for the target environment. Check for AEC-Q100 qualification if automotive reliability reports are required.

Selection Notes

Select this part when low quiescent current is critical alongside high-voltage input tolerance. The -1 suffix provides one inverting and one noninverting input, suitable for window comparator configurations. Compare against LT6700IS6-1#TRPBF if the 36V input capability is unnecessary, as it offers lower power consumption. Verify package availability in TSOT-23.

Part Context

This component belongs to the LT6700/LT6700HV family of micropower comparators. The 'HV' variant distinguishes itself by supporting inputs and outputs up to 36V, whereas standard versions are limited to 18V. The 'I' suffix denotes industrial temperature performance. The 'S6' indicates the 6-lead TSOT-23 thin plastic package.

Replacement Considerations

LT6700IS6-1#TRPBF serves as a direct substitute if the 36V input rating is not required, offering lower power consumption.
