Overview
The TSM973CUA+ is a dual-channel, ultra-low-power analog comparator manufactured by Silicon Labs. It operates on single supplies from +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 supports adjustable external hysteresis via the HYST pin. It utilizes open-drain outputs for wired-OR configurations and exhibits a propagation delay of 12μs at 10mV overdrive. The component is housed in an 8-pin MSOP package.
Feature Summary
- Dual comparators integrated with an internal precision voltage reference
- Open-drain output stages enabling wired-OR logic applications
- Adjustable hysteresis capability through dedicated input pin
- Ultra-low quiescent current consumption suitable for battery-powered systems
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery switchover circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging type and temperature range. Confirm that the component meets RoHS compliance standards as indicated by the plus sign in the part number. Ensure the supply chain source provides valid traceability for the manufacturer's lead-free program specifications.
Selection Notes
Select this component when dual comparators are required alongside a stable internal reference voltage. It is appropriate for designs needing adjustable hysteresis without additional external components. Verify that the application requires open-drain outputs and operates within the specified single or dual supply voltage ranges.
Part Context
This device belongs to the TSM97x/98x family of low-voltage micropower analog comparators. It serves as an alternate source for the MAX973 device. The family includes single, dual, and quad variants with varying reference accuracies and hysteresis capabilities across different package types.
Replacement Considerations
TSM973CUA+ is electrically and form-factor identical to the MAX973. Other family members like TSM971 or TSM982 may be considered if channel count or reference accuracy requirements differ.
