The MAX16913/MAX16913A high-voltage high-side
current-sense switches feature internal current limiting
to prevent system damage due to fault conditions. The
MAX16913/MAX16913A input voltage range extends
from 5V to 18V, making them ideal for providing phantom
power to remote radio-frequency low-noise amplifiers
(LNAs) in automotive applications.
The MAX16913/MAX16913A monitor the load current
and provide an analog output voltage proportional to
the sensed load current. In addition to current sensing,
accurate internal current-limiting circuitry protects the
input supply against both overload and short-circuit
conditions. Two open-drain fault indicator outputs notify
the microprocessor when a short circuit, an open-load
condition, or a short-to-battery condition exists. For the
MAX16913A, the open-load threshold is externally
adjustable using a resistive divider.
