INA229AIDGSR

Current Regulation/Management Overview

The INA229AIDGSR is a high-precision current and power monitor manufactured by Texas Instruments. It features a 20-bit analog-to-digital converter with an SPI digital interface for data output. The device operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating supply current of 5 mA. It provides measurement accuracy of 0.5% across the specified temperature range. The component supports bidirectional current measurements and is housed in a VSSOP-10 surface-mount package.

Current Regulation/Management Feature Summary

• Integrates a 20-bit ADC for high-resolution current and power monitoring
• Provides serial peripheral interface (SPI) communication for digital data access
• Supports bidirectional current sensing capabilities

Current Regulation/Management Applications

• Industrial process control systems
• Power management unit monitoring
• Battery management systems

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DGSR' confirms the VSSOP-10 package and tape-and-reel shipping configuration. Confirm that the 'I' designation indicates the industrial temperature grade suitable for the required operational environment. Ensure compatibility with the host system's SPI protocol settings before integration.

Current Regulation/Management Selection Notes

Select this component when high resolution and precision are required for DC current monitoring applications. The integrated SPI interface simplifies connection to microcontrollers compared to analog-output alternatives. Consider the 5 mA supply current consumption relative to system power budgets, as it is higher than some low-power counterparts.

Current Regulation/Management Part Context

This part belongs to the INA229 family of current and power monitors from Texas Instruments. It is designed for applications requiring precise measurement of voltage, current, and power. The device complements other sensors in power management architectures by providing accurate digital feedback for regulation and protection loops.
