Description
The MPQ7931 is a power management IC (PMIC) designed to meet the power management requirements of processors used in various safety-relevant automotive systems.
Six integrated synchronous buck converters can be configured as 3 dual-phase or 6 single-phase converters. With dynamic voltage scaling, the output voltage (VOUT) of each converter can be changed during normal operation. The serial interface provides packet error checking (PEC) and an integrated memory to allow a high degree of configurability.
Six enable pins allow each regulator to be sequenced independently for flexible timing control. This allows the device to meet a wide variety of sequencing requirements. To prevent overshoot during start-up, soft-start (SS) functionality is featured on each converter, and the slew rate can be configured.
A 2MHz, fixed-frequency pulse-width modulation (PWM) control regulates VOUT, offers fast transient response performance, and significantly reduces external inductance and capacitance. Frequency spread spectrum (FSS) reduces EMI noise. The full protection suite includes under-voltage lockout (UVLO), over-current protection (OCP), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown.
The MPQ7931 is available in a QFN-32 (5mmx5mm) package.
