INA208AIPWR

Current Regulation/Management Overview

The INA208AIPWR is a high-side current sense amplifier from Texas Instruments, designed for bidirectional current and power monitoring. It operates with an input voltage range of -16 V to 80 V and features a fixed gain of 100 V/V. The device integrates dual comparators and a precision voltage reference, offering ±3.5% accuracy over the specified temperature range. Powered by a single supply between 2.7 V and 5.5 V, it consumes only 1 mA of quiescent current. Housed in a 14-pin TSSOP package, it supports industrial temperatures from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrated dual comparators for window monitoring without external components
• Bidirectional sensing capability for both sourcing and sinking currents
• Built-in precision voltage reference for accurate measurement scaling

Current Regulation/Management Applications

• Battery management systems requiring high-side current monitoring
• Industrial motor control and protection circuits
• Power distribution units with overcurrent detection needs

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PW' confirms the 14-pin TSSOP package variant. Ensure the operating environment stays within the -40°C to +125°C thermal limits. Confirm that the system common-mode voltage does not exceed the 80 V maximum rating. Check for moisture sensitivity level requirements during storage and handling procedures.

Current Regulation/Management Selection Notes

Select this component when a fixed 100 V/V gain is required for high-side applications. It is suitable for designs needing integrated comparator functionality to simplify bill of materials. Consider the -16 V to 80 V input range compatibility with standard bus voltages. Evaluate the 1 mA quiescent current against strict power budget constraints.

Current Regulation/Management Part Context

Part of the INA20x family of unidirectional and bidirectional current shunt monitors. This series provides complete solutions by combining amplification, comparison, and reference functions. The INA208 specifically targets applications requiring higher gain compared to the INA206 or INA207 variants.

Current Regulation/Management Replacement Considerations

INA206AIPWR offers 20 V/V gain. INA207AIPWR provides 50 V/V gain. Both share similar packages and pinouts but differ in amplification factors.
