Overview
The TS9001-1IJ5 is a nanopower analog comparator from Silicon Labs, operating on a single supply voltage ranging from 1.6V to 5.5V. It features a push-pull output stage and an internal reference voltage of 1.252V with ±1% accuracy. The device draws a typical supply current of 600nA at 1.6V. Input voltages can extend 200mV beyond the power rails without phase reversal. It includes 4mV of internal hysteresis for clean switching and is housed in a 5-pin SC70 package.
Feature Summary
- Push-pull output stage designed for rail-to-rail swings and minimal supply-current surges during transitions.
- Robust input stage tolerates differential input voltages extending 200mV outside the supply rails.
- Internal 1.252V reference provides stable thresholding without external components.
- Integrated 4mV internal hysteresis prevents oscillation near trip points.
Applications
- Two-cell battery monitoring and management systems
- Medical instruments requiring ultra-low power consumption
- Threshold detectors and discriminators
- Sensing applications at ground or supply lines
Procurement Notes
Verify the specific ordering suffix 'IJ5' against the manufacturer's official documentation to confirm the tape and reel packaging configuration. Confirm that the component meets RoHS compliance standards as indicated in the datasheet. Ensure the SC70-5 package dimensions align with your PCB layout requirements before finalizing procurement.
Selection Notes
Select the TS9001-1 variant specifically when a push-pull output is required for driving loads directly between supply rails. This model is suitable for applications needing rail-to-rail output swing and higher output drive capability compared to open-drain alternatives. Consider the internal reference if external precision voltage sources are unavailable or cost-prohibitive.
Part Context
The TS9001 series belongs to Silicon Labs' NanoWatt Analog portfolio, designed for high-performance low-power applications. It serves as a functional equivalent to the MAX9117 family, offering improved electrical performance and form-factor compatibility. The series targets mobile communications and remote telemetry systems where battery life is critical.
Replacement Considerations
The TS9001-1 is electrically identical to the Maxim Integrated MAX9117. Verify pinout and parameter alignment when substituting this part with the MAX9117 in existing designs.
FAQ
Does the TS9001-1 support input voltages exceeding the supply rails?
Yes, the input voltage range extends 200mV beyond both the positive (VCC) and negative (VEE) supply rails without causing phase reversal.
What is the function of Pin 4 on the TS9001-1?
Pin 4 serves as the REF/IN- terminal, providing access to the internal 1.252V reference output or acting as the comparator's inverting input.
