Remote Antenna Current-Sense
Amplifier and Switches
/MX6913A
General Description
Features
♦ Switch Phantom Power-On/-Off Under µC Control
♦ Analog Current Measurement Output
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 phan-
tom power to remote radio-frequency low-noise ampli-
fiers (LNAs) in automotive applications.
♦ 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,
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.
♦ Thermal Shutdown
♦ AEC-Q100 Qualified (/V Versions Only)
♦ -40°C to +105°C Operating Temperature Range
Typical Operating Circuits
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,
preventing 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.

Remote Antenna Current-Sense
Amplifier and Switches
The AOUT voltage is clamped to typically 4.3V in order
to avoid damage to external circuitry.
Detailed Description
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 phan-
tom power to remote radio-frequency low-noise ampli-
fiers (LNAs) in automotive applications. High-side
current monitoring does not interfere with the ground
path of the load being measured, making these
devices particularly useful in a wide range of high-volt-
age battery-powered systems.
Load Protection
The MAX16913/MAX16913A monitor the load current
through an external sense resistor and perform the fol-
lowing actions:
•
If the monitored current is lower than the open-load
current, the device signals open load (see the
Open Load section).
•
If the monitored current is higher than the short-cir-
cuit current (I ), the device enters the short-circuit
SC
mode (see the Short Circuit section).
The MAX16913/MAX16913A monitor the load current
by means of a high-side current-sense amplifier and
provide an analog output voltage proportional to that
current at AOUT.
The devices also perform a short-to-battery detection
every time the internal switch turns on (see the Short-to-
Battery Detection section). In addition, thermal shut-
down protects the MAX16913/MAX16913A from
overheating (see the Thermal Shutdown section). Two
open-drain outputs (OL and SC) indicate the device
status (see Table 1).
The devices combine a high-side current-sense amplifi-
er, an internal switch, a +3V bandgap reference, and
two open-drain fault indicator outputs. These features
enable the design of remote power circuits with short-
circuit, short-to-battery, and thermal protection. For the
MAX16913A, the open-load threshold is externally
adjustable using a resistive divider.
Open Load
If the load current drops below the open-load current
threshold, the OL output asserts low. An open-load
condition does not turn off the internal switch. The
MAX16913 provides an internally fixed open-load
threshold, while the MAX16913A features an adjustable
open-load threshold.
/MX6913A
A fault-blanking feature enables the circuit to ignore
momentary faults, such as those caused by initial
charging of a capacitive load at turn-on, preventing
false alarms to the system.

The MAX16913/MAX16913A provide an active-high

For the MAX16913A, using a resistive divider between
REF, the open-load threshold adjustment pin (OLT),
and GND sets the open-load threshold (see the Open-
Load Threshold Selection section).

Thermal shutdown circuitry protects the devices from

Short-to-Battery Detection
It may happen that OUT is shorted to the battery due to
a fault in the system. The MAX16913/MAX16913A
detect this failure by comparing the OUT voltage and
the IN voltage before the switch turns on. Every time
the switch turns on, such as at the end of the retry time,
or once the thermal shutdown condition disappears,
the short-to-battery detection is performed. At this
Shutdown (SHDN)
The MAX16913/MAX16913A feature an active-high con-
trol input (SHDN) to put the devices in a low-power shut-
down mode. The devices turn off and consume only 5µA
(max) of shutdown current when SHDN is driven high.

Input Capacitor

has a large high-frequency component.
SENSE
Connect a low-leakage ceramic capacitor from IN to
GND to limit the input voltage drop during momentary
output short-circuit conditions, and to protect the
device against transients due to inductance in the IN
line. For example, use at least a 0.1µF ceramic capaci-
tor if the input inductance (including any stray induc-
tance) is estimated to be 20µH. Larger capacitor values
reduce the voltage undershoot at the input.
Wire-wound resistors have the highest inductance,
while metal film is somewhat better. Low-inductance
metal-film resistors are also available. Instead of being
spiral wrapped around a core, as in metal-film or wire-
wound resistors, they are a straight band of metal and
are available in values under 1Ω. Because of the high
current that flows through R
, avoid parasitic trace
SENSE
resistance from causing errors in the sense voltage.
Output Capacitor
In an analogous fashion to the input capacitor, an out-
put capacitor protects the device against transients
due to any series inductance in the output. Under no
conditions should the OUT pin voltage go below -0.3V
as specified in the Absolute Maximum Ratings. If a
capacitor alone is not sufficient to avoid large negative
transients on OUT, then a Schottky diode should be
used to clamp transients which go below ground. With
a 100µH output series inductor, a 220µF output capaci-
tor is needed to eliminate potential problems. With larg-
er inductor values or smaller capacitors, a Schottky
clamp diode will be necessary.
Open-Load Threshold Selection
For the MAX16913A, a resistive divider between REF,
OLT, and GND sets the open-load threshold. See
Figure 3.
Use the following formula to set the desired open-load
threshold:
(R
(Ω)× I (A)× A (V/V))+ 0.4V

Layout and Thermal Dissipation
To optimize the switch response time to output short-
circuit condition, it is very important to keep all traces
as short as possible to reduce the effect of undesirable
parasitic inductance. Place input and output capacitors
as close as possible to the device (no more than 5mm).
and R should be large enough so that the output
impedance of the internal reference (5kΩ) is negligible
compared to the sum of R and R , and has a minimum

threshold.

IN and OUT must be connected with wide short traces
to the power bus. During normal operation, the power
dissipation is small and the package temperature
change is minimal. If the output is continuously shorted
to ground at the maximum supply voltage, the devices
are protected because the total power dissipated dur-
ing the short is scaled down by the duty cycle imposed
by the protection:
