Overview
The TSM971CUA+T is a single-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 with ±1% accuracy and adjustable hysteresis via the HYST pin. It draws a maximum quiescent current of 4μA over temperature. The output stage is open-drain, supporting wired-OR configurations. Propagation delay is 12μs at 10mV overdrive. Available in 8-pin MSOP and SOIC packages.
Feature Summary
- Ultra-low quiescent current consumption suitable for battery-powered systems
- Integrated 1.182V voltage reference with high precision
- Open-drain output stages enabling wired-OR logic applications
- Adjustable external hysteresis capability for noise immunity
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific package variant (MSOP or SOIC) required for your PCB footprint when ordering. Confirm that the C suffix meets your operating temperature range requirements. Ensure compatibility with existing supply voltages within the specified 2.5V to 11V single-supply range. Check for lead-free compliance if necessary for assembly processes.
Selection Notes
Select this component for designs requiring minimal power consumption and integrated reference voltage. Consider the open-drain output when designing pull-up resistor networks. Evaluate the need for adjustable hysteresis to prevent oscillation in noisy environments. Verify input common-mode voltage ranges against your signal levels.
Part Context
This part belongs to the TSM97x family of micropower analog comparators. It serves as an alternate source for Maxim Integrated MAX971 devices. The family includes dual and quad variants like the TSM972 and TSM973. These components are designed for low-voltage, space-constrained applications.
Replacement Considerations
The TSM971CUA+T is electrically identical to the Maxim Integrated MAX971CSA+. Designers can substitute one for the other without circuit modifications. Verify package compatibility between MSOP/SOIC options during replacement.
FAQ
How is hysteresis configured on the TSM971?
Hysteresis is adjusted using two external resistors connected to the HYST pin. Connecting HYST directly to the REF pin disables hysteresis.
What is the input voltage range?
The input voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
