The threshold for short detection current can be adjusted with an external resistor! It flexibly accommodates various GPS antennas.
The "CA0027AN" is an IC that supplies power to the GPS antenna and monitors the current to diagnose the connection status of the GPS antenna and output an alarm signal. The threshold for short detection current can be adjusted using an external resistor. Additionally, the limit current is determined in conjunction with this, allowing for flexible compatibility with various GPS antennas. 【Features】 ■ Adjustable threshold for short detection current ■ Flexible compatibility with various GPS antennas ■ Open collector output ■ Automotive compatible (AEC-Q100 Grade-2 compliant) *For more details, please refer to the PDF document or feel free to contact us.
