MPQ7933-AEC1

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

详情

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.

MPQ7932-AEC1 基于 MPSafe^TM开发流程的5.5V电源管理IC，带 6 个降压变换器，符合 AEC-Q100 认证

MPQ7932-AEC1 是一款电源管理 IC (PMIC)，专为满足各种汽车系统中的处理器电源管理需求而设计。

该器件集成了6 个同步降压变换器，可配置为 3 轨双相变换器或 6 轨单相变换器。通过动态电压调节，每个变换器的输出电压 (V_OUTx) 都可以在正常运行期间变化。MPQ7932-AEC1还提供带数据包错误校验 (PEC)功能的PMBus接口，并集成多页一次性可编程(MOTP)存储器以实现高度可配置性。

每个变换器都具有软启动 (SS) 功能，以防止启动期间出现过冲；还具有软关断功能，以实现关断期间的正常放电。软启动/软关断斜率均可通过数字寄存器配置。

MPQ7932-AEC1中包含了可配置的窗口或Q&A看门狗定时器、专用 WDI 引脚、外部电压监视器以及时序输出引脚。它通过固定频率、2MHz 峰值电流模式控制来调节 V_OUTx，同时具备快速瞬态响应性能，可大幅降低外部电感和电容需求。此外，该器件还提供频谱扩展 (FSS)功能以降低 EMI 噪声，同时提供全面的保护功能，包括欠压锁定 (UVLO)保护、欠压保护 (UVP)、过压保护 (OVP) 和过温关断保护。

MPQ7932-AEC1 采用 TQFN-32（5mmx5mm）封装，符合 AEC-Q100 等级1认证。
