MPQ5873GRPE-AEC1-Z

The MPQ5873-AEC1 is a smart high-side load switch for nominal 3A loads. The device supports a wide 3.5V to 36V input voltage (VIN) range. With a small on resistance (RDS(ON)), the MPQ5873-AEC1 provides a highly efficient, compact solution. The MPQ5873-AEC1 supports both an internal and configurable, high-accuracy external current limit. This helps clamp the inrush current under short-circuit conditions, which improves overall system reliability. An adjustable start-up slew rate also helps to reduce inrush current during start-up. The FT/CS pin provides high-accuracy current sensing, which achieves accurate real-time diagnostics without additional calibration. The voltage on the FT/CS pin (VCS) represents 1 / KCS of the load current (ILOAD), where KCS is a constant value across the temperature and supply voltage ranges. The FT/CS pin can report faults by pulling up its voltage. The MPQ5873-AEC1 features full diagnostics during both on and off states. By pulling the DIAG_EN pin up or down, off-state open-load and short-to-battery detection can be enabled or disabled, respectively. If off-state diagnostics are not required in the system, the function can be disabled to reduce the standby current by connecting the DIAG_EN and GND pins. The MPQ5873-AEC1 is available in a QFN-8 (2mmx2.5mm) package. It is available in AEC-Q100 Grade 1 and is compliant with AEC-Q100-012 Test Grade A.
