The AD8214 is a fast response, high common-mode voltage, current shunt comparator. The device operates on the high side rail of any DC current sensing application, provided the voltage is between 5 V and 65 V. Internally, the AD8214 features a fast comparator that is optimized for high side operation. An internal Zener regulator powers the circuit with respect to the high side DC rail. In addition, user access to this 2.4V regulator, allows for setting a comparator threshold voltage via external resistors. The AD8214 will compare the voltage across the shunt resistor to this user-selected threshold, and the AD8214 output will change states from low to high, indicating the current across the shunt has crossed the threshold level.

The input to output response time of the AD8214 is typically less than 100 ns. This makes the device optimal for overcurrent protection in applications such as motor and solenoid control. Built-in comparator hysteresis means that once the current across the shunt falls back to a normal limit, the AD8214 output will change states to its original level.

The AD8214 is available in an 8-lead MSOP package. The operating temperature range is −40°C to +125°C, and the device is fully qualified for automotive applications.
