MPQ7932-AEC1

The EVQ7932-UT-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7932-AEC1, a power management IC (PMIC) designed to meet the power management requirements of processors used in various safety-relevant automotive systems. 

The six integrated, synchronous buck converters can be configured to operate as three-rail, dual-phase converters, or they can operate as six-rail, single-phase  converters. With dynamic voltage scaling, the output voltage of each converter (V_OUTx, where x = 1 to 6) can be changed during normal operation. The PMBus interface provides packet error checking (PEC), and the integrated multi-page, one-time-programmable (MOTP) memory allows for a high degree of configurability. 

To prevent overshoot during start-up, soft-start (SS) functionality is featured on each converter. In addition, to allow for proper discharge during shutdown, soft-stop functionality is featured on each converter. The slew rate for both functions can be configured via the digital registers. 

The MPQ7932-AEC1 also features a configurable windowed or Q&A watchdog, dedicated WDI pin, external voltage monitor, and sequence output pin. 

A 2MHz, fixed-frequency, 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. The full protection suite features under-voltage lockout (UVLO), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown. 

The EVQ7932-UT-00A is a fully assembled and tested evaluation board. The MPQ7932-AEC1 is available in a TQFN-32 (5mmx5mm) package with wettable flanks. It is AEC-Q100 qualified.
