Overview
The TSM931CUA+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 ±2% voltage reference and adjustable hysteresis via the HYST pin. Quiescent current is typically 3.2µA at 25°C, rising to 4µA over the full temperature range. Propagation delay is 12µs at 10mV overdrive. The push-pull output stage supports TTL/CMOS compatibility with continuous source current capability up to 40mA.
Feature Summary
- Integrates an internal 1.182V ±2% voltage reference for simplified circuit design.
- Features adjustable external hysteresis through a dedicated HYST pin to prevent oscillation.
- Provides crowbar-current-free switching to minimize glitches during output transitions.
- Delivers high continuous source current capability suitable for direct load driving.
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify component authenticity against official datasheets as this part serves as an alternate source for legacy MAX931 devices. Confirm package integrity for the 8-MSOP form factor. Check for specific ordering suffixes that may indicate variations in packaging or carrier types. Ensure compliance with RoHS standards and lead-free requirements specified by the manufacturer.
Selection Notes
Select this component when low quiescent current consumption is critical for battery-operated designs. The integrated reference eliminates the need for external voltage sources. Verify that the required propagation delay meets system timing constraints. Ensure the input common-mode voltage range aligns with the application's signal levels relative to the supply rails.
Part Context
This device belongs to the TSM931-TSM934 family of micropower analog comparators. It is electrically and form-factor identical to the MAX931-MAX934 series. The 'C' suffix indicates an industrial temperature range of 0°C to +70°C. The 'UA' designation specifies the 8-pin MSOP package type.
Replacement Considerations
The TSM931CUA+T is functionally equivalent to the Maxim Integrated MAX931. Designers replacing legacy MAX931 components can use this part without modifying the schematic due to electrical and form-factor identity.
