TS9001-1IJ5T

Overview

The TS9001-1IJ5T is a nanopower analog comparator manufactured by Silicon Laboratories, distributed under the Touchstone Semiconductor brand. It operates on supply voltages from 1.6V to 5.5V with a typical supply current of 600nA at 1.6V. The device features a push-pull output stage capable of driving 5mA loads and includes an internal 1.252V ±1% voltage reference. Input voltages extend 200mV beyond the supply rails without phase reversal. It is housed in a 5-pin SC70 package.

Feature Summary

• Ultra-low power consumption with 600nA supply current for extended battery life
• Robust input stage tolerates voltages 200mV outside the supply rails
• Integrated 1.252V precision voltage reference with internal hysteresis
• Push-pull output stage designed to minimize supply-current surges during switching

Applications

• 2-cell battery monitoring and management systems
• Medical instruments requiring low-power operation
• Threshold detectors and discriminators
• Sensing applications at ground or supply lines
• Mobile communications and telemetry remote systems

Procurement Notes

Verify that the component is sourced from authorized distributors to ensure authenticity. Confirm the part marking matches the datasheet specifications. Check for lead-free packaging compliance as specified by the manufacturer. Ensure the operating temperature range meets your system requirements.

Selection Notes

Select this comparator for applications demanding minimal quiescent current and small footprint. The push-pull output is suitable for direct logic interfacing. Consider the open-drain variant if wired-OR configurations are required. Verify that the internal reference accuracy meets your threshold detection needs.

Part Context

This component belongs to the NanoWatt Analog portfolio, designed for high-performance, low-power analog integrated circuits. It serves as a drop-in replacement for specific MAX9117/MAX9118 family members with improved electrical performance. The product line focuses on enabling longer battery life in portable electronic devices.

Replacement Considerations

The TS9001-1 is electrically identical to the MAX9117. Designers replacing these parts should verify pin compatibility and ensure the new source provides equivalent propagation delay characteristics under similar load conditions.

FAQ

Does the TS9001-1 suffer from phase reversal when inputs exceed the supply rails?

No, the robust input stage design ensures no phase reversal occurs even when input voltages extend 200mV beyond the power supply rails.

What is the purpose of the internal hysteresis in this comparator?

The internal 4mV hysteresis prevents oscillation in the linear region caused by circuit noise or parasitic feedback, ensuring clean switching behavior without external components.
