TSM102AIPWR

Overview

The TSM102AIPWR is a monolithic integrated circuit combining dual operational amplifiers, dual comparators, and a precision voltage reference. It operates within a supply voltage range of 3 V to 30 V and supports an operating temperature from -40 °C to 85 °C. The device features a gain-bandwidth product of 2.1 MHz and a slew rate of 2 V/µs. Input offset voltage is typically 1 mV with a drift of 10 µV/°C. The voltage reference provides a nominal output of 2.5 V with A-grade tolerance of ±0.4% at 25 °C.

Feature Summary

• Integrates dual op-amps, dual comparators, and a precision adjustable voltage reference in a single package
• Operational amplifiers feature rail-to-rail input common-mode voltage range including ground
• Comparators provide low-level output saturation voltage close to the negative supply rail
• Voltage reference offers high sink current capability ranging from 1 mA to 100 mA

Applications

• Switch-mode power supplies
• Battery chargers
• Window comparators
• Alarms, detectors, and sensors

Procurement Notes

Verify the specific 'A' grade designation for the tighter 0.4% voltage reference tolerance compared to standard grades. Confirm the PW (TSSOP) package type matches the target PCB footprint and soldering profile requirements. Ensure the reel quantity aligns with production volume needs. Cross-reference the manufacturer part number against official Texas Instruments documentation to confirm authenticity and current production status before finalizing orders.

Selection Notes

Select this component when space and cost savings are required by consolidating multiple analog functions into one IC. The TSM102AIPWR is suitable for applications needing medium-speed signal processing alongside precise voltage monitoring. Consider the 200 µA per amplifier supply current for low-power designs. Verify that the 6 mA output current capability meets load requirements for both the op-amps and comparators in the intended circuit topology.

Part Context

This device belongs to the TSM102 family of special purpose amplifiers manufactured by Texas Instruments. It serves as a versatile building block for implementing various power-management functions such as overcurrent detection, undervoltage/overvoltage detection, and power-good signaling. The integration reduces component count and simplifies board layout compared to using discrete amplifiers and references.

Replacement Considerations

Direct substitutes include TSM102IDR and TSM102IPWR for standard grade performance. For SOIC packages, consider TSM102AIDR. Verify pin compatibility and electrical specifications match application requirements when transitioning between these variants.
