MPQ7932-AEC1

MPSafe^TM-Compatible, 5.5V PMIC with 6 Buck Converters, AEC-Q100 Qualified

概要

The MPQ7932-AEC1 is a power management IC (PMIC) designed to meet the power management requirements of processors used in various automotive systems.

The PMIC integrates six synchronous buck converters, which can be configured to function as three-rail, dual-phase or six-rail, single-phase converters. With dynamic voltage scaling, the output voltage (V_OUTx) of each converter can be changed during normal operation. The PMBus interface with packet error checking (PEC) and an integrated multi-page, one-time programmable (MOTP) memory allows for a high degree of configurability.

To prevent overshoot during start-up, each converter features soft start (SS) functionality. To allow proper discharge during shutdown, each converter also features soft shutdown functionality. The slew rate for both functions is configurable via the digital registers.

A configurable windowed or Q&A watchdog, dedicated WDI pin, external voltage monitor, and sequence output pin are all included. Fixed-frequency, 2MHz peak current mode control regulates V_OUTx, offers fast transient performance, and allows for a large reduction in external inductance and capacitance. Frequency spread spectrum (FSS) reduces EMI noise. A full protection suite features under-voltage lockout (UVLO), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown.

The MPQ7932-AEC1 is available in a TQFN-32 (5mmx5mm) package, and is available in AEC-Q100 Grade 1.
