MPQ70152FS-AEC1数据手册MPS中文资料规格书

描述 Description

The MPQ70152FS-AEC1 is a low-noise, high switching frequency (fSW) power management integrated circuit (PMIC) optimized for powering monolithic microwave integrated circuits (MMICs) in automotive radar applications.

Features include two individual step-down DC/DC converters and one boost converter with excellent transient performance and high efficiency. The step-down DC/DC converters support configurable fSW up to 17.6MHz to enable LDO-free, low-noise power solutions with minimal or no passive filtering. The configurable frequency spread spectrum (FSS) function can dither fSW for improved EMI performance. 

Safety mechanisms such as built-in self-testing (BIST) provide high diagnostic coverage, which helps the system achieve its target ASIL rating. It has been developed under MPS's advanced MPSafeTM Functional Safety Product Development process, which has been independently certified to meet ISO 26262 guidelines. 

A configurable watchdog timer is implemented with window and Q&A modes. Built-in voltage monitoring is featured for the input voltage (VIN) and output voltage (VOUT) rails. An additional voltage monitor is included to monitor an external rail. Protection features include VIN and VOUT under-voltage lockout (UVLO), over-voltage protection (OVP), under-voltage protection (UVP), output short-circuit protection (SCP), and thermal shutdown (TSD). Both SPI and I2C digital interfaces, as well as one-time programmable (OTP) memory, are featured for configurability and flexibility.

The MPQ70152FS-AEC1 requires minimal external components, and is available in a thermally enhanced TQFN-28 (5mmx5mm) package. It is available in AEC-Q100 Grade 1.
