TS9001-2IJ5T

Overview

The TS9001-2IJ5T is a nanopower analog comparator manufactured by Silicon Labs, housed in a 5-pin SC70 package. It guarantees operation down to +1.6V with a supply current of 600nA. The device features an internal +1.252V ±1% reference and an open-drain output stage. Input voltages extend 200mV outside the rails without phase reversal. Operating temperature range is -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with 600nA supply current
• Internal 1.252V voltage reference with ±1% accuracy
• Robust input stage tolerating voltages beyond supply rails
• Open-drain output stage for flexible logic interfacing

Applications

• 2-cell battery monitoring and management systems
• Medical instruments requiring low-power threshold detection
• Threshold detectors and discriminators
• Sensing at ground or supply lines
• Telemetry and remote systems

Procurement Notes

Verify component authenticity through authorized channels as the TS9001-2IJ5T is listed as obsolete by Mouser. Confirm lead-free packaging status and check for valid replacement options from Silicon Labs due to end-of-life status. Ensure compatibility with existing SC70 footprints if substituting.

Selection Notes

Select this component for applications demanding minimal quiescent current and small form factors. The open-drain output requires an external pull-up resistor. Verify that the required hysteresis meets the 4mV internal specification or design additional external feedback if higher noise immunity is needed for specific signal conditions.

Part Context

This part belongs to the TS9001 Nanopower Comparator family, which includes the push-pull TS9001-1 variant. Both share identical electrical performance and form factor but differ in output stage configuration. The TS9001 series represents Silicon Labs' entry into high-performance nano-watt analog integrated circuits designed for extreme power efficiency.

Replacement Considerations

The datasheet states the TS9001-1/2 are electrically and form-factor identical to the MAX9117 and MAX9118 families.
