Overview
The TSM973CUA+T is a dual-channel analog comparator from the TSM97x family, manufactured by Touchstone Semiconductor (Silicon Labs). It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features an internal 1.182V reference voltage with ±1% accuracy and open-drain outputs suitable for wired-OR configurations. Key electrical parameters include a maximum propagation delay of 12µs at 10mV overdrive, a maximum supply current of 6µA, and an input offset voltage of ±10mV. It is housed in an 8-pin MSOP package.
Feature Summary
- Integrates an internal 1.182V voltage reference with high precision.
- Features adjustable external hysteresis via a dedicated HYST pin.
- Supports wired-OR logic through open-drain output stages.
Applications
- Threshold detectors
- Window comparators
- Level translators
Procurement Notes
Verify the manufacturer as Touchstone Semiconductor or Silicon Labs. Confirm the package type is 8-MSOP. Ensure the suffix matches the tape-and-reel configuration if required. Check for lead-free compliance status.
Selection Notes
Select this component for low-power applications requiring dual comparators and a built-in reference. It is suitable for battery-powered systems where quiescent current must be minimized. Verify that the open-drain output topology fits the system's pull-up requirements.
Part Context
This part belongs to the TSM97x series of ultra-low-power comparators. It serves as an alternate source for the Maxim MAX973. The family includes single, dual, and quad variants with varying reference accuracies and temperature ranges.
Replacement Considerations
The datasheet identifies the MAX973 as the primary equivalent part. Verify pin compatibility and electrical specifications before substitution.
FAQ
How is hysteresis configured on the TSM973?
Hysteresis is adjusted using two external resistors connected between the REF, HYST, and V- pins. Connecting HYST directly to REF disables hysteresis.
What is the input common-mode voltage range?
The inputs accept signals ranging from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
