Overview
The TSM933ESA+ is a dual-channel analog comparator from Silicon Labs, part of the TSM93x family. It operates on single supplies from +2.5V to +11V or dual supplies from ±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 reference with ±2% accuracy and supports adjustable external hysteresis via a dedicated pin. Quiescent current is limited to 6μA maximum over temperature.
Feature Summary
- Dual-channel architecture with integrated voltage reference
- Push-pull output stages compatible with TTL and CMOS logic
- Adjustable hysteresis capability for noise immunity
- Ultra-low quiescent current consumption
Applications
- Window comparators
- Threshold detectors
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm package integrity upon receipt. Ensure proper handling procedures are followed during storage and assembly to maintain electrical characteristics.
Selection Notes
Select this component when dual independent comparison channels are required within a single package. The integrated reference simplifies circuit design by reducing external component count. Verify that the supply voltage range aligns with system requirements and that the output drive capability meets load specifications.
Part Context
This device belongs to the TSM931-TSM934 family of micropower comparators. It is electrically and form-factor identical to the MAX931-MAX934 series. The family offers flexibility in channel count and packaging options to suit various low-voltage applications.
Replacement Considerations
The MAX933 is a confirmed substitute part number due to electrical and form-factor identity. Verify pinout compatibility and operating conditions before implementation.
FAQ
How is hysteresis configured on the TSM933?
Hysteresis is added externally using two resistors connected to the HYST pin. Connecting HYST to REF disables hysteresis.
What is the input common-mode voltage range?
The input voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
