Overview
The TSM921CUA+T is a single-channel, ultra-low-power analog comparator from Silicon Labs. It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA and sinking 5mA continuously. It includes an internal 1.182V ±1% reference voltage and supports adjustable external hysteresis via a dedicated pin. Quiescent current is typically under 4μA over temperature.
Feature Summary
- Ultra-low quiescent current consumption suitable for battery-powered systems
- Integrated 1.182V precision voltage reference with source/sink capability
- Push-pull output stage providing high continuous current drive without crowbar glitches
- Dedicated pin for configuring external positive feedback hysteresis
Applications
- Threshold detectors and window comparators
- Battery-powered monitoring systems
- Level translators and oscillators
Procurement Notes
Verify the specific suffix 'CUA+' corresponds to the commercial temperature range (0°C to +70°C) and 8-pin MSOP package. Confirm that the '+T' designation indicates tape and reel packaging rather than tube. Ensure compatibility with existing board layouts as this component is electrically identical to the MAX921 family.
Selection Notes
Select the TSM921CUA+T when a single comparator with an integrated reference and adjustable hysteresis is required. This part is appropriate for designs needing high output drive capability while maintaining microampere-level power consumption. Consider the TSM923 if dual channels are needed, or the TSM922/TSM924 if multiple comparators are required without internal references.
Part Context
This component belongs to the TSM92x family of micropower analog comparators manufactured by Silicon Labs. The family shares electrical characteristics with the Maxim Integrated MAX92x series but is supplied under the Silicon Labs brand. The TSM921 variant specifically provides one comparator channel within an 8-lead mini-small-outline package.
Replacement Considerations
The TSM921CUA+T is electrically and form-factor identical to the Maxim Integrated MAX921CUA+T. These parts can be substituted directly in existing designs without circuit modification.
