The MPQ5871 is designed as a smart high-side power switch for a nominal 1A load. The device supports a wide 3.5V to 36V input voltage (V_IN) range. The MPQ5871 provides a highly efficient and compact solution with a small on resistance (R_DS(ON)).

The device supports both an internal current limit and a configurable, high-accuracy external current limit. These limits clamp the inrush current under short-circuit conditions, which improves system reliability. An adjustable start-up slew rate also helps to reduce the inrush current during start-up

The FT/CS pin provides high-accuracy current sensing, which achieves accurate diagnostics in real time without additional calibration. The voltage on the FT/CS pin represents (1 / K_CS) of the load current, where K_CS is a constant value across the temperature and supply voltage ranges. The FT/CS pin can report faults by pulling up its voltage.

The MPQ5871 provides full diagnostic capabilities when it is in both on and off states. By pulling the DIAG_EN pin up or down, users can enable or disable off-state open-load or battery short detection. If the system does not require off-state diagnostics, turn off this function and reduce the standby current by connecting the DIAG_EN pin to the GND pin.

The MPQ5871 is available in a QFN-8 (2mmx2.5mm) package, and it is available in AEC-Q100 Grade 1 and AEC-Q100-012 Test Grade A.
