GPS antenna diagnosis IC

CA0027AN

CA0027AN

Product name

GPS antenna diagnosis IC

Ovewview

CA0027AN is an IC that supplies power to GPS antenna, and outputs alarm signal by diagnosing connection status (Open/Short-circuit) of GPS antenna by monitoring current.
The threshold for short-circuit detection current can be adjusted by external resistor.
Limit current is determined along with the threshold, and the IC supports various GPS antenna flexibly.
It has acquired AEC-Q100 Grade-2 and can be used for in-vehicle devices.

Features

Package type SON-8pin 2.2mm × 2.2mm 0.5mm pitch
Power supply voltage 3V to 5.5V (Maximum ratings 7.0V)
Antenna supply voltage VCC-0.28V(antenna current20mA)
Open detection current 4.5mA(typ)
Short-circuit detection current 25mA to 70mA(typ)
Operating ambient temperature -40℃~105℃
Quality AEC-Q100 Grade-2 qualified
