Overview
19-4186; Rev 0; 7/08 KIT ATION EVALU E L B AVAILA Remote Antenna Current-Sense Amplifier and Switches General Description Features ♦ 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 ♦ Thermal Shutdown ♦ AEC-Q100 Qualified (/V Versions Only) ♦ -40°C to +105°C Operating Temperature Range MAX16913/MAX16913A 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.
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 thermaloverload 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.
The MAX16913/MAX16913A are available in the 16-pin QSOP package and operate over the -40°C to +10...
