MPQ70241FS-AEC1

The MPQ70241FS-AEC1 is a power management IC (PMIC) solution integrating three high-efficiency step-down DC/DC converters and a low-noise low-dropout (LDO) regulator. Its dual-stage, 18V buck architecture maximizes efficiency for the 1.8V image sensor I/O rail in the CMOS sensor in high-resolution camera modules. Constant-on-time (COT) control with phase-locked loop (PLL) provides a fast transient response time. During continuous conduction mode (CCM), the fixed 2.2MHz switching frequency (fSW) greatly reduces external inductor and capacitor sizes. The digital interface allows for application flexibility. The output voltage (VOUT), power sequence, and protection thresholds can all be adjusted via the interface. Fault statuses can also be monitored. Protection features include under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown (TSD). The MPQ70241FS-AEC1 supports applications with a high automotive safety integrity level up to ASIL-B. Functional safety features include analog built-in self-testing (ABIST), diagnostics, and a PG output pin. The MPQ70241FS-AEC1 is developed under MPS's advanced MPSafeTM functional safety product development process, which has been independently certified to meet ISO 26262 guidelines. The MPQ70241FS-AEC1 minimizes external component count and is available in a space-saving QFN-15 (2.5mmx3.5mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
