High Side/Low Side, Current Sense Comparator "INA301"
The INA301 is a high-speed, high-precision current sense amplifier with a built-in comparator and overcurrent protection functionality. It features a high common-mode current detection amplifier and a fast comparator, measuring the voltage that develops across a current sensing resistor or current shunt resistor, and detects overcurrent conditions by comparing the measured voltage with a defined threshold limit. The threshold range can be adjusted with a single external limit-setting resistor. The current shunt monitor can measure differential voltage signals with a common-mode voltage of 0V to 36V, regardless of the supply voltage. It has an open-drain alert output, which can be configured to operate in either transparent mode (output status follows input state) or latch mode (alert output is cleared when the latch is reset). With a response time of less than 1µs, it can quickly detect the occurrence of overcurrent. It operates with a single supply voltage of 2.7V to 5.5V, with a maximum supply current of 700µA. It has an extended operating temperature range of -40°C to +125°C, and the package is an 8-pin VSSOP-10. *For more details, please contact us.
