TSM102IPWR

Overview

The TSM102IPWR is a monolithic integrated circuit featuring two operational amplifiers, two comparators, and a precision voltage reference. It operates on a supply voltage range of 3 V to 30 V with a total supply current of 2 mA (excluding reference cathode current). The operational amplifiers provide a gain-bandwidth product of 2.1 MHz and a slew rate of 2 V/µs. The device includes a voltage reference with a nominal output of 2.5 V and standard grade tolerance of 1%. It is housed in a 16-pin TSSOP package.

Feature Summary

• Integrates dual operational amplifiers, dual comparators, and a precision voltage reference into a single monolithic IC.
• Operational amplifiers feature rail-to-rail input common-mode voltage range including ground.
• Comparators offer low-level output saturation voltage close to the negative supply rail.
• Voltage reference provides adjustable output voltage capability from V_REF up to 36 V.

Applications

• Switch-Mode Power Supplies
• Battery Chargers
• Window Comparators

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP package type and 'R' indicates tape-and-reel packaging configuration. Confirm that the 'I' suffix denotes the industrial temperature range (-40°C to 85°C) as specified in the manufacturer's ordering information. Ensure compatibility with the required lead finish and moisture sensitivity level ratings for your assembly process.

Selection Notes

Select this component when space and cost savings are required for power management functions such as overcurrent detection or undervoltage alarms. The device is suitable for applications needing both analog signal processing via op-amps and threshold detection via comparators. Consider the standard 1% voltage reference tolerance if higher precision than the A-grade variant is not necessary.

Part Context

The TSM102 series combines essential building blocks for implementing wide varieties of power-management functions. It serves as an alternative to using discrete components for error amplifiers, window comparators, and power-good detection circuits. The family includes variants with different package options and voltage reference tolerances.
