Sample & Buy Product Folder Support & Community Tools & Software Technical Documents INA301 SBOS713 – SEPTEMBER 2015 1 Features 3 Description • • • The INA301 includes both a high common-mode current-sensing amplifier as well as a high-speed precision comparator configured to detect overcurrent conditions through measuring the voltage developed across a current-sensing or shunt resistor. This current shunt monitor can measure this differential voltage signal on common-mode voltages that can vary from 0 V up to 36 V, independent of the supply voltage. The device features an adjustable threshold range that is set using a single external limit-setting resistor. 1 • • • • • Wide Common-Mode Input Range: 0 V to 36 V Dual Output: Amplifier and Comparator Output High Accuracy Amplifier: – Offset Voltage: 100 µV – Offset Voltage Drift: 0.5 µV/°C – Gain Error: 0.15% – Gain Error Drift: 10 ppm/°C Available Amplifier Gains: – INA301A1: 20 V/V – INA301A2: 50 V/V – INA301A3: 100 V/V Programmable Threshold Set Through a Single Resistor Total Alert Response Time: 1 µs Open-Drain Output With Latching Mode Package: MSOP-8 2 Applications • • • • • • Overcurrent Protection Power-Supply Protection Circuit Breakers Computers and Servers Telecom Equipment Battery Management An open-drain alert output on the device can be configured to operate in either a transparent mode where the output status follows the input state or in a latched mode where the alert output is cleared when the latch is reset. The device alert response time is issued in under 1 µs to allow for quick detection of overcurrent events. This device operates from a single 2.7-V to 5.5-V supply, drawing a maximum supply current of 700 µA. The device is specified over the extended operating temperature range (–40°C to +125°C), and is available in an MSOP-8 package.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device.
