MAX16946GTE/V+

The MAX16946GTE/V+ by Analog Devices (Maxim Integrated) is a high-voltage, high-side, current-sense LDO/switch. It is designed to prevent system damage with internal current limiting capabilities. The MAX16946 offers a fixed 8.5V output or an adjustable output voltage ranging from 3.3V to 15V. It can also be configured as a switch.

With an input voltage range of 4.5V to 18V (45V tolerant), this device is suitable for providing phantom power to remote radio-frequency low-noise amplifiers in automotive applications. It monitors load current and provides an analog output voltage proportional to the sensed current. The device protects the input supply against overload and short-circuit conditions. It includes open-drain fault indicator outputs to signal short circuits or open-load conditions.

The MAX16946 operates over a temperature range of -40°C to +105°C and is available in a 16-pin TQFN-EP package. It features short-to-battery protection and thermal shutdown for robust operation. An active-low shutdown input allows for low-power shutdown mode.

Key features include precision adjustable current limit, current measurement analog voltage output, and fault-blanking to ignore momentary faults. It is AEC-Q100 qualified.
