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 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.
The MAX16913/MAX16913A are available in the 16-pin QSOP package and operate over the -40°C to +105°C temperature range.
