概述

Description

The INA190A5IRSWR is a Texas Instruments high-side current-sense amplifier. It measures the small voltage across a low-value shunt resistor placed in the high side of a load and provides a amplified output suitable for ADCs or microcontrollers. It uses a fixed gain (no external resistors needed), so you don’t need external gain-setting components.
Key features (typical): wide input common-mode range (up to around 65 V), single-supply operation from about 2.7 V to 5.5 V, low input offset and fast response for current sensing, and built‑in protection (input overvoltage/short-circuit, etc.). The A5IRSWR suffix denotes a specific grade/package variant.
Applications: automotive and industrial power management, motor control, battery management, and DC-DC converter monitoring.
Implementation notes: place the sense resistor close to the load, keep sense traces short, provide proper supply decoupling, and scale the fixed gain output to your ADC’s input range.

Features

Here are the key features of the INA190A5IRSWR (TI) in brief:
- High-side current-sense amplifier for measuring across a shunt resistor
- Fixed-gain current-to-voltage output (output voltage proportional to sensed current)
- Wide supply range: supports 2.7 V to 5.5 V
- Rail-to-rail output suitable for single-supply systems
- Wide input common-mode range (extends up to the high-side voltage)
- Low input offset and low bias current for accurate measurements
- High CMRR and PSRR for reliable operation in noisy environments
- Fast response/bandwidth for dynamic load transients
- Robust protection features (overload/thermal protection)
- Small 8-pin package (SWR/WSON-style) suitable for compact designs
Note: For exact gain values per variant and precise electrical specs (offset, CMRR, bandwidth, quiescent current, etc.), please refer to the TI datasheet for INA190A5IRSWR.

Package

The INA190A5IRSWR is in an 8-pin VSSOP package (3.0 × 3.0 mm), RoHS-compliant, supplied in Tape-and-Reel.

Pinout

8 pins. It is a high-side current-sense monitor (current shunt monitor) with a current-output stage: it senses the voltage across a shunt resistor at IN+ and IN− and delivers an output current (Iout) proportional to the sensed voltage; use an external resistor to convert Iout to a voltage. Power pins: V+, GND (and typically a REF pin in some variants).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits; one of the world’s largest semiconductor makers.

Application

- High-side, bidirectional current sensing for automotive and industrial power management
- Battery monitoring and protection
- Motor control and DC-DC converter sensing
- Overcurrent and current-limit protection
- Power supplies, chargers, and solar inverters
- Energy meters and portable devices

Equivalent

Closest equivalents:
- TI: other INA190 variants (A1–A5 share the same pinout/specs). Functionally similar TI parts: INA199 and INA210 high-side current-sense monitors.
- Analog Devices: AD8210/AD8211/AD8215 high-side current-sense amplifiers (0–100 mV shunt input).
Exact cross depends on your required gain, supply range, and packaging.
