TSM102AIPW

Overview

The TSM102AIPW is a monolithic integrated circuit from Texas Instruments housed in a 16-pin TSSOP package. It integrates two operational amplifiers, two comparators, and an adjustable 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 parameters include a gain-bandwidth product of 2.1 MHz, a typical slew rate of 2 V/µs, and a low supply current of 200 µA per amplifier. The voltage reference offers A-grade precision with a tolerance of 0.4% at 25 °C.

Feature Summary

• Integrates dual operational amplifiers, dual comparators, and a precision voltage reference into a single monolithic IC for space and cost savings.
• Features rail-to-rail input common-mode voltage range that includes ground potential.
• Provides low-level output saturation voltage close to the negative supply rail.
• Includes latch-up immunity for enhanced reliability in power management applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-16 tube packaging configuration. Confirm the 'A' grade designation ensures the tighter 0.4% voltage reference tolerance required for your application. Check the latest Package Option Addendum for current production status and moisture sensitivity level ratings before finalizing procurement plans.

Selection Notes

Select this component when a combined solution for signal conditioning and voltage referencing is needed. The TSM102AIPW is suitable for designs requiring low quiescent current and high common-mode rejection. Ensure the 16-pin TSSOP footprint fits the PCB layout constraints. Compare against standard grade parts if the 1% reference tolerance is sufficient for lower-cost requirements.

Part Context

This part belongs to the TSM102 family of special purpose amplifiers manufactured by Texas Instruments. The family combines multiple analog building blocks to simplify power management circuit designs. The TSM102A variant specifically denotes the A-grade version with improved voltage reference accuracy compared to the standard TSM102 grade.
