MAX16913/MAX16913A

Remote Antenna Current-Sense

Amplifier and Switches

General Description

Features

The MAX16913/MAX16913A high-voltage high-side cur-

rent-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.

● Switch Phantom Power-On/-Off Under μC Control

● Analog Current Measurement Output

● Adjustable Current Limiting (340mA Maximum)

● Detect Open-Load and Short-Circuit Conditions

● Provide Open-Drain Fault Signals (SC and OL)

● Overcurrent Blanking During Startup

The MAX16913/MAX16913A monitor the load current

and provide an analog output voltage proportional to the

sensed load current. In addition to current sensing, accu-

rate internal current-limiting circuitry protects the input

supply against both overload and short-circuit conditions.

Two open-drain fault indicator outputs notify the micro-

processor 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.

● Thermal Shutdown

● AECQ100 Qualified (/V Versions Only)

● -40°C to +105°C Operating Temperature Range

Typical Application Circuits

BATTERY

INPUT

PROTECTED

LOAD (LNA)

A fault-blanking feature enables the circuit to ignore

momentary faults, such as those caused by the initial

charging of a capacitive load when hot swapping, prevent-

ing false alarms to the system. Built-in thermal-overload

protection turns off the switch when the die temperature

exceeds +150°C (min). The MAX16913/MAX16913A also

feature a short-to-battery detection every time the internal

switch turns on. These devices provide an active-high

control input to put the devices in low-power shutdown

mode.
