Overview
The TSM932CSA+ is a dual-channel analog comparator manufactured by Silicon Labs, housed in an 8-pin SOIC package. It operates on single supplies from +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 continuously. It includes an internal 1.182V ±2% voltage reference and supports adjustable external hysteresis via a dedicated pin. Quiescent current is limited to 6μA maximum over the industrial temperature range.
Feature Summary
- Dual-channel configuration with integrated 1.182V reference
- Push-pull output stages compatible with TTL and CMOS logic
- Adjustable hysteresis capability through dedicated control pin
- High continuous source current capacity for direct load driving
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify component authenticity against official Silicon Labs documentation due to its status as an alternate source for legacy MAX93x devices. Confirm that the specific ordering suffix aligns with required packaging and temperature specifications. Ensure compatibility with existing board layouts designed for the original manufacturer's footprint and electrical characteristics.
Selection Notes
Select this component when dual independent comparison channels are required within a compact 8-pin form factor. It is suitable for applications needing a stable internal reference voltage without external components. Consider the 40mA output drive capability if direct interfacing with low-impedance loads is necessary. Verify supply voltage ranges match the system architecture requirements.
Part Context
This part belongs to the TSM931-TSM934 family of ultra-low-power comparators. It is electrically and form-factor identical to the MAX931-MAX934 series produced by Maxim Integrated. The TSM932 variant specifically provides two comparators per package, distinguishing it from the single-channel TSM931 and quad-channel TSM934 options.
Replacement Considerations
- MAX932CPE+
- MAX932CPD+
FAQ
How is external hysteresis configured on the TSM932?
External hysteresis is added using two resistors connected to the HYST pin. Connecting the HYST pin directly to the REF pin 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+).
