MPQ5870L-AEC1

28V, 0.5A, Single-Channel, Smart High-Side Load Switch with High-Accuracy Current Sense, AEC-Q100 Grade 1 Qualified

概要

The MPQ5870L-AEC1 is designed as a smart high-side power switch for a nominal 0.5A load. The device supports a wide 5V to 28V input voltage (V_IN) range. It provides a highly efficient and compact solution with a small on resistance (R_DS(ON)).

As a functional safety capable device, the MPQ5870L-AEC1 provides related safety documentation to aid in functional safety design. The device supports both internal current limits and configurable, high-accuracy external current limits. It helps to 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 CS/FT pin provides high-accuracy current-sensing (CS), which achieves accurate, real-time diagnostics without further calibration. The CS/FT pin voltage (V_CS/FT) represents 1/KCS of the load current, where KCS is a constant value across the temperature and supply voltage ranges. Meanwhile, the CS/FT pin can report a fault by pulling up its voltage.

Full diagnostics during both on and off states have been developed for the MPQ5870L-AEC1. By pulling the DIAG_EN pin up or down, the diagnostic functions (CS, off-state open-load/short-to-battery detection) can be enabled or disabled. If an off-state diagnostic is not required in the system, the function can be disabled by connecting it to the EN pin to further reduce the quiescent current (I_Q).

The MPQ5870L-AEC1 is available in QFN-8 (2mmx2.5mm) and SOT583 packages, and is available in AEC-Q100 Grade 1 and AEC-Q100-012 Test Grade A.
