Overview
The TSM932ESA+T is a dual-channel, low-voltage micropower analog comparator manufactured by Silicon Labs. It operates from single +2.5V to +11V or dual ±1.25V to ±5.5V supplies with a maximum quiescent current of 6µA over temperature. The device features push-pull TTL/CMOS-compatible outputs capable of sourcing 40mA continuously and includes an internal 1.182V ±2% voltage reference. It offers adjustable hysteresis via a dedicated pin, input voltage range including the negative supply rail, and crowbar-current-free switching in an 8-SOIC package.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Adjustable external hysteresis capability
- Push-pull outputs compatible with TTL and CMOS logic
- Micropower operation with ultra-low quiescent current
Applications
- Threshold detectors
- Window comparators
- 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 that the ordering suffix '+T' corresponds to the tape and reel packaging format required for automated assembly processes. Ensure compatibility with existing design specifications regarding the 8-SOIC footprint and electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel comparator with an internal reference is required for low-power applications. It serves as an alternate source for the MAX932 family. Consider the 8-SOIC package constraints and verify that the 40mA output drive capability meets load requirements. Ensure the operating temperature range aligns with system environmental conditions.
Part Context
This device belongs to the TSM93x family of ultra-low-power comparators, which are electrically and form-factor identical to the MAX931-MAX934 series. The family includes single, dual, and quad variants, all sharing similar low-voltage operation and micropower characteristics designed for efficient performance in portable and battery-operated electronic systems.
Replacement Considerations
The TSM932ESA+T is an alternate source for the Maxim Integrated MAX932ESA+T. Verify pinout and electrical parameter equivalence before substitution. Check for any specific manufacturing changes documented in Product Change Notices (PCN) related to packaging or material composition updates.
FAQ
How is external hysteresis configured on the TSM932?
External hysteresis is added using two resistors connected to the HYST pin. Connecting HYST to REF disables hysteresis, while applying a voltage between REF and REF-50mV generates up to 50mV of hysteresis.
What is the input voltage range of the TSM932?
The input voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
