INA186A4QDBVRQ1

Overview

The INA186A4QDBVRQ1 is a unidirectional, low-power current sense amplifier from Texas Instruments. It features a fixed gain of 200 V/V and operates with a supply voltage between 1.7 V and 5.5 V. The device supports common-mode voltages from -0.2 V to +40 V and draws a maximum quiescent current of 90 µA. It offers a minimum common-mode rejection ratio of 120 dB and a maximum gain error of ±1%. The component is housed in an SOT-23-5 package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

Unidirectional current sensing capability
Low input bias current for high accuracy
Rail-to-rail output swing
High common-mode rejection

Applications

Body control module (BCM)
Telematics control unit
Emergency call (eCall)
12-V battery management system (BMS)
Automotive head unit

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification and the 'A4' designation ensures the 200 V/V gain setting. Confirm the 'DBV' package corresponds to the SOT-23-5 form factor required for the design. Ensure the datasheet revision matches the intended production timeline as specifications may evolve.

Selection Notes

Select this part when a fixed 200 V/V gain is required for unidirectional monitoring. The SOT-23-5 package lacks a reference pin, restricting operation to unidirectional mode only. Consider the 33 kHz bandwidth and 90 µA maximum supply current against system power and speed constraints.

Part Context

This component belongs to the INA186-Q1 family of automotive-grade current sense amplifiers. It shares the same core architecture and electrical characteristics as other variants in the series, differing primarily in fixed gain options and package configurations. The family is designed for cost-sensitive automotive systems requiring high precision.
