Current Sense Comparator "INA300"
The INA300 is a 36V low-side/high-side overcurrent protection comparator. It is a current sensing comparator for overcurrent protection applications that measures the voltage across a shunt resistor and detects overcurrent by comparing that voltage to a threshold voltage input level. It measures differential voltage signals with a common mode voltage of 0V to 36V, regardless of the supply voltage. The threshold range can be adjusted with a single external setting resistor. With a selectable hysteresis function, the comparator's operation can be adjusted to accommodate a wide input signal range of 0mV to 250mV. It features an open-drain alert output that can operate in either transparent mode (output status follows input state) or latch mode (alert output is cleared when the latch is cleared). The response time is selectable, allowing for overcurrent alerts to be triggered in as little as 10µs. It operates on a single supply voltage of 2.7V to 5.5V, with a maximum supply current of 135µA. It has an extended operating temperature range of -40°C to +125°C, and is available in WSON-10 and VSSOP-10 packages. *For more details, please contact us.*
