The MPQ5884-AEC1 is an automotive-grade, low-resistance e-fuse and smart high-side power switch with low quiescent current (IQ) mode. It is designed for demanding applications such as high-current relay replacements and fuse replacements. Protection and diagnostic features improve system robustness and performance.
It uses proprietary, fuse-like over-current protection (OCP), which can emulate the behavior ofa passive fuse. Current-sensing and temperature-sensing allow the switch’s status to be monitored. Open-load detection monitors the load’s health. Low-IQ mode can help prolong the battery life when the system is in sleep mode.
The MPQ5884-AEC1 provides robust protections including OCP, short-circuit protection (SCP), loss of IC GND, loss of module GND, loss of power supply, over-temperature protection (OTP), reverse battery self-protection, and reverse load protection.
The device can survive under severe transient pulses. When a bidirectional TVS diode is applied in the system, the MPQ5884-AEC1 can handle the tests defined in ISO 7637-2, ISO 16750-2,and ISO 21780. It turns on the MOSFET under a negative input voltage (VIN) to achieve the same current capability under a positive VIN, and features a 4.5mΩ, rugged power N-channel MOSFET.
The MPQ5884-AEC1 is available in a QFN-30 (5mmx6mm) package, and is available in AEC-Q100 Grade 1.
