TSM102IPW

Overview

The TSM102IPW is a mixed-signal integrated circuit housed in a 16-pin TSSOP package. It integrates a dual operational amplifier, a dual comparator, and a precision voltage reference. The device operates within a supply voltage range of 3 V to 30 V and supports an operating temperature range from -40 °C to 85 °C. Key electrical characteristics include a typical total supply current of 1.5 mA per amplifier at 5 V, a gain-bandwidth product of 2.1 MHz for the op-amp, and a reference voltage tolerance of 1% for the standard grade.

Feature Summary

• Combines dual operational amplifiers, dual comparators, and a precision voltage reference in a single package
• Operational amplifiers feature low supply current consumption and input common-mode voltage range including ground
• Comparators provide low output saturation voltage close to the negative supply rail
• Voltage reference offers adjustable output capability with high sink current capacity

Applications

• Switch-Mode Power Supplies
• Battery Chargers
• Voltage and Current Sensing Circuits
• Power-Good, Overvoltage, Undervoltage, and Overcurrent Detection Systems
• Window Comparators and Alarm Detectors

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity. The 'PW' suffix indicates the TSSOP-16 package. Ensure the grade matches application requirements, as the 'I' suffix denotes standard 1% precision. Confirm RoHS compliance and moisture sensitivity level ratings before procurement. Cross-reference the manufacturer's latest packaging addendum for accurate shipping dimensions and tape-and-reel specifications.

Selection Notes

Select the TSM102IPW when space-constrained designs require multiple analog functions. It is suitable for applications needing both signal amplification and threshold detection alongside a stable reference. Consider the A-grade variant if tighter voltage reference tolerance is required. Evaluate thermal performance based on the TSSOP package thermal impedance. Ensure the supply voltage stays within the 3 V to 30 V range for optimal operation.

Part Context

This component belongs to the TSM102 family, which includes variants like the TSM102AID and TSM102AIPW. These devices are designed for power management tasks where combining discrete components into a single IC reduces board space and complexity. The family supports both SOIC and TSSOP packages, catering to different assembly and density requirements.

Replacement Considerations

Direct substitutes include other TI parts from the same family, such as TSM102AID or TSM102AIPW, depending on the required precision grade and package style. Verify pin compatibility and electrical parameters against the original design requirements before substitution.
