INA303A2IPWR

Current Regulation/Management Overview

The INA303A2IPWR is a high-speed precision current sense amplifier manufactured by Texas Instruments. It operates within an input voltage range of 0V to 36V and supports bidirectional current sensing for both high-side and low-side applications. The device features selectable gains of 20 V/V, 50 V/V, and 100 V/V. It includes integrated comparators with alert functions and offers a minimum common-mode rejection ratio (CMRR) of 100 dB. The component is housed in a 14-TSSOP package and is rated for operation between -40°C and 125°C.

Current Regulation/Management Feature Summary

• Provides selectable gain options including 20 V/V, 50 V/V, and 100 V/V
• Delivers high common-mode rejection ratio for accurate measurements

Current Regulation/Management Applications

• Overcurrent protection circuits
• High-speed precision current monitoring
• Battery management systems
• Power supply regulation

Current Regulation/Management Procurement Notes

Verify the specific suffix 'A2' confirms the required gain configuration before procurement. Ensure the 'IPWR' designation matches the 14-TSSOP surface-mount package requirement. Confirm RoHS3 compliance status if environmental regulations apply to the target assembly. Cross-reference the datasheet revision to ensure compatibility with existing design specifications.

Current Regulation/Management Selection Notes

Select this component when bidirectional sensing capability is required alongside integrated fault detection. The fixed gain options eliminate external resistor networks, simplifying board layout. Consider the 14-TSSOP footprint constraints during mechanical design. Verify that the 36V input range aligns with the system's maximum common-mode voltage requirements.

Current Regulation/Management Part Context

This part belongs to the INA303 family of current sense amplifiers from Texas Instruments. It shares the core architecture with the INA302 but offers enhanced performance characteristics. The A2 suffix specifically denotes the gain configuration variant within the product line. It is designed as a direct replacement for legacy high-speed current sensing solutions requiring integrated alerts.

Current Regulation/Management Replacement Considerations

The INA303A2IPW is the non-reel version of the same functional device. For automotive applications, the INA303A2QPWRQ1 provides equivalent electrical performance with AEC-Q100 qualification.
