Programmable Alert Threshold Set Through a Single Resistor
Total Alert Response Time: 1 µs
Open-Drain Output With Latching Mode
Description for the INA301
The INA301 includes both a high common-mode, current-sensing amplifier and a high-speed comparator configured to detect overcurrent conditions through measuring the voltage developed across a current-sensing or current-shunt resistor and comparing that voltage to a defined threshold limit. The device features an adjustable limit threshold range that is set using a single external limit-setting resistor. This current-shunt monitor can measure differential voltage signals on common-mode voltages that can vary from 0 V up to 36 V, independent of the supply voltage.
The open-drain alert output 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 under 1 µs, allowing 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 8-pin VSSOP package.
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
