MPQ7933-AEC1

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

Description

The MPQ7933-AEC1 is a power management IC (PMIC) designed meet the power management requirements of processors used in various safety-relevant automotive systems.

The six integrated, synchronous buck converters can be configured as 3-rail dual-phase or 6-rail single-phase converters. With dynamic voltage scaling, the output voltage (V_OUTx, where x = 1~6) of each converter can be changed during normal operation. The PMBus interface provides packet error checking (PEC) and an integrated multi-page one-time programmable (MOTP) memory, which allows for a high degree of configurability.

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

The MPQ7933-AEC1 also features a configurable windowed or Q&A watchdog and dedicated WDI pin, an external voltage monitor, and a sequence output pin. 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 MPQ7933-AEC1 is available in a TQFN-32 (5mmx5mm) package, and is available in AEC-Q100 Grade 1.
