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癈 to +125癈, and the device
is fully qualified for automotive applications.
