TSM9119EXK+T

Overview

The TSM9119EXK+T is a nanopower analog comparator from the TSM9117-TSM9120 family, manufactured by Silicon Labs. It operates on a single supply voltage ranging from +1.6V to +5.5V and draws a typical supply current of 350nA at +1.6V. The device features a push-pull output stage capable of driving loads with rail-to-rail swings. It includes internal hysteresis for clean switching and robust input stages that tolerate voltages extending 200mV beyond the supply rails without phase reversal.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Robust input stage allowing operation 200mV outside the supply rails
• Push-pull output drivers designed to minimize supply-current surges during transitions
• Internal hysteresis prevents oscillation in linear regions

Applications

• Two-cell battery monitoring and management
• Medical instruments
• Threshold detectors and discriminators
• Sensing at ground or supply lines
• Mobile communications and telemetry systems

Procurement Notes

Verify the specific ordering suffix '+T' corresponds to the tape and reel carrier configuration as documented in the manufacturer's ordering information. Confirm lead-free packaging compliance and ensure the SC-70-5 package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when an internal voltage reference is not required, distinguishing it from the TSM9117/TSM9118 variants. Choose the push-pull output version over open-drain types if direct rail-to-rail drive capability is needed without external pull-up resistors. Ensure the application voltage remains within the guaranteed 1.6V minimum operating range.

Part Context

This part belongs to the TSM9117-TSM9120 series of nanopower comparators, which are electrically and form-factor identical to the MAX9117-MAX9120 family. The TSM9119 specifically denotes the variant without an internal reference but retaining the push-pull output architecture, offering lower quiescent current compared to the reference-equipped counterparts.

Replacement Considerations

The datasheet explicitly states this component is a second-source for the Maxim Integrated MAX9119. Verify pinout compatibility and electrical specifications against the original MAX9119 datasheet to ensure functional equivalence in existing designs.
