INA204AIDR

Current Regulation/Management Overview

The INA204AIDR is a high-speed current shunt monitor manufactured by Texas Instruments, housed in a 14-SOIC package. It supports both low-side and high-side measurements with an input voltage range of -16 V to 80 V. The device operates on a supply voltage between 2.7 V and 18 V, drawing a typical operating supply current of 1 mA. It features a precision accuracy of ±3.5% and includes dual comparators with an internal reference. The component functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports high-side and low-side current sensing across a wide common-mode voltage range
• Integrates dual comparators with an internal reference for system protection
• Provides high-speed voltage output proportional to the sensed current

Current Regulation/Management Applications

• Industrial process control systems requiring precise current monitoring
• Power distribution units for circuit protection and management
• Battery management systems in portable and stationary equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix 'IDR' corresponds to the 14-SOIC surface-mount package and tape-and-reel packaging configuration. Confirm that the 'A' grade designation meets the required ±3.5% accuracy specifications for your application. Ensure compatibility with the -40°C to +125°C operating temperature range. Check for moisture sensitivity level requirements during storage and handling procedures.

Current Regulation/Management Selection Notes

Select this component when both current monitoring and comparator-based protection are needed in a single package. The wide input voltage range allows flexibility in system design without level shifting. Consider the 14-pin SOIC footprint for PCB layout constraints. Evaluate the 1 mA supply current against total power budget limitations in battery-operated devices.

Current Regulation/Management Part Context

This part belongs to the INA20x family of current shunt monitors from Texas Instruments. It complements other variants like the INA202 and INA203 by offering integrated comparators. The family targets applications requiring robust current sensing with built-in fault detection capabilities in industrial and commercial environments.
