INA193AMDBVREPG4

Current Regulation/Management Overview

The INA193AMDBVREPG4 is a high-side current shunt monitor manufactured by Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It features a wide common-mode voltage range of -16 V to 80 V, allowing accurate measurement in high-voltage environments. The device offers a fixed gain of 20 V/V and a bandwidth of 500 kHz. Key electrical specifications include an input offset voltage of 2 mV, input bias current of 23 uA, and a CMRR of 100 dB. It operates on a supply voltage between 2.7 V and 18 V with a typical quiescent current of 950 uA. The component is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to +125°C.

Current Regulation/Management Procurement Notes

Verify that the specific suffix 'EP' denotes enhanced product status or specific manufacturing lot requirements as defined by Texas Instruments. Confirm AEC-Q100 qualification compliance for automotive integration. Ensure the SOT-23-5 package matches the PCB footprint design. Cross-reference the datasheet revision to confirm pinout and electrical characteristics align with the target application requirements before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when high-side current sensing is required in automotive environments with voltages up to 80 V. The fixed 20 V/V gain simplifies design for standard ADC inputs. Consider the 500 kHz bandwidth for dynamic load applications. The low quiescent current aids in energy-efficient system designs. Ensure the thermal performance of the SOT-23-5 package meets the junction temperature limits for the intended operating environment.

Current Regulation/Management Part Context

This part belongs to the INA193 family of current shunt monitors from Texas Instruments. It is specifically qualified for automotive use, distinguishing it from commercial variants like the INA193AIDBVR. The 'EP' suffix typically indicates an enhanced product designation, often relating to specific quality or lifecycle management criteria set by the manufacturer for long-term availability in critical applications.

Current Regulation/Management Replacement Considerations

Direct substitutes within the same family include the INA193AIDBVRG4 for commercial applications, though it lacks automotive qualification. For non-automotive replacements, verify if the standard INA193A series meets the voltage and accuracy requirements. Always check package compatibility and gain settings when swapping parts.
