GENERAL DESCRIPTION  
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.
