INA236BIYBJR

Current Regulation/Management Overview

The INA236BIYBJR is a 16-bit digital current monitor and power regulator from Texas Instruments, designed for high-precision monitoring applications. It features an I²C/SMBus compatible interface and supports bus voltages up to 48V with a common-mode range of -0.3V to 48V. The device operates on a single supply voltage ranging from 1.7V to 5.5V, consuming a typical operating current of 300µA and reducing to 2.2µA in standby mode. It provides programmable full-scale ranges of 20mV or 80mV, ensuring accurate current measurement with a maximum gain error of 0.1% and offset of 5µV. The component utilizes a DSBGA-8 package (0.745mm × 1.508mm) and includes configurable averaging options and alert limits for overcurrent, undervoltage, and overvoltage conditions.

Current Regulation/Management Feature Summary

• Integrates 16-bit ADC resolution with internal multiplication for direct current and power value reporting without external processing.
• Supports both high-side and low-side current detection across a wide common-mode voltage range independent of supply voltage.
• Features four programmable I²C addresses via the A0 pin, allowing multiple devices on a single bus.
• Includes hardware-level alert triggers for overcurrent, undervoltage, and overvoltage events with configurable thresholds.

Current Regulation/Management Applications

• Battery management systems and cell monitoring
• Server power health monitoring
• Industrial PLC modules
• Smart metering front-ends

Current Regulation/Management Procurement Notes

Verify the specific suffix 'BIYBJR' against the manufacturer's official datasheet to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with system I²C voltage levels and address configuration requirements before integration. Cross-reference the RoHS status and lead-free compliance details provided in the latest production documentation to meet regulatory standards.

Current Regulation/Management Selection Notes

Select this component when precise 16-bit current and power monitoring is required within a 48V bus environment. It is suitable for designs needing low standby power consumption and integrated alert functionality. Consider the DSBGA-8 footprint constraints and thermal performance during PCB layout. Verify that the required I²C address space does not conflict with other devices on the same communication bus.

Current Regulation/Management Part Context

The INA236 belongs to Texas Instruments' family of digital current monitors, offering enhanced precision compared to analog alternatives. The 'B' variant typically denotes specific accuracy or temperature range characteristics within the series. This model integrates analog front-end capabilities with digital signal processing, simplifying system architecture by eliminating the need for external microcontrollers to perform real-time power calculations.

Current Regulation/Management Replacement Considerations

Check for direct substitutes within the INA236 series or compatible INA226/INA230 models if pinout and interface requirements align. Verify that alternative components support the same 48V common-mode range and 16-bit resolution. Ensure that any replacement maintains the DSBGA-8 package dimensions or requires PCB re-layout.
