MPQ71000FS-AEC1

MPSafe^TM ASIL-D, 36V, 300mA, Dual LDO with ADC and I²C Interface, AEC-Q100 Qualified

Description

The MPQ71000FS-AEC1 is a dual-channel, low-dropout (LDO) regulator with an I²C interface and one-time programmable (OTP) memory. The device provides power for automotive advanced driver-assistance systems (ADAS) module and active antennas in automotive systems. The wide input voltage (V_IN) range makes the MPQ71000FS-AEC1 suitable for battery cold-crank (3V) conditions, up to load dump (42V) conditions.

The MPQ71000FS-AEC1 delivers up to 300mA of current per channel with excellent load and line regulation. The dual LDO output voltages (V_OUT1 and V_OUT2) are both configurable via the I²C interface with a range between 1V and 18V. The standard I²C interface provides flexibility in applications. Various parameters can be adjusted by writing the settings in the device without any hardware changes required.

The MPQ71000FS-AEC1 has an internal successive approximation register (SAR) analog-to-digital converter (ADC) to monitor output voltage and current, as well as the temperature. The device is provides full diagnostics of over-current (OC), short-circuit (SC), output over-voltage (OV), under-voltage (UV), short-to-battery (STB), and open-load conditions. It also features thermal shutdown.

Safety mechanisms such as built-in self-testing (BIST) provide high diagnostic coverage, which provides the desired safety coverage for ASIL-D requirements.

The MPQ71000FS-AEC1 is available in flip-chip QFN-14 (3mmx3mm) and wire-bonded QFN-16 (4mmx4mm) packages with wettable flanks. It is available in AEC-Q100 Grade 1.
