TSM9117EXK+T

Overview

The TSM9117EXK+T is a nanopower analog comparator from the TSM9117 family, manufactured by Silicon Labs. It features an internal 1.252V reference and a push-pull output stage. The device guarantees operation down to +1.6V with a supply current of 600nA at 1.6V. Input voltages extend 200mV beyond the rails without phase reversal. It includes 4mV internal hysteresis for clean switching and crowbar-current-free transitions. The component is supplied in a 5-pin SC70 package.

Feature Summary

• Guaranteed operation down to +1.6V with ultra-low supply current consumption
• Integrated 1.252V ±1.75% voltage reference
• Push-pull output driver capable of driving 5mA loads
• Input voltage range extends 200mV outside-the-rails

Applications

• 2-cell battery monitoring and management
• Medical instruments
• Threshold detectors and discriminators
• Sensing at ground or supply line
• Ultra-low-power systems

Procurement Notes

Verify the specific ordering suffix EXK+T against the manufacturer's official documentation to confirm the tape and reel packaging configuration. Confirm that the component meets RoHS compliance requirements as specified in the datasheet. Ensure the source is authorized to prevent counterfeit parts, as this component may have limited availability due to its status.

Selection Notes

Select the TSM9117EXK+T when a push-pull output is required for direct load driving up to 5mA. Choose this part over open-drain variants if rail-to-rail output swings are necessary. Consider the integrated 1.252V reference for simplified threshold setting. Verify that the 600nA supply current meets the power budget constraints of the target application.

Part Context

This component belongs to the TSM9117-TSM9120 family of nanopower comparators. It is electrically and form-factor identical to the MAX9117-MAX9120 series. The family includes variants with and without internal references, as well as push-pull and open-drain output options. All members share robust input stages and low supply current characteristics suitable for battery-powered devices.

Replacement Considerations

The TSM9117EXK+T is a second-source equivalent for the MAX9117. Verify pinout compatibility and electrical specifications before substitution. Check for differences in operating temperature ranges or packaging moisture sensitivity levels.
