MPQ70700FS-AEC1数据手册MPS中文资料规格书

描述 Description

The MPQ70700FS-AEC1 is a functional safety power management IC (PMIC) designed to power a variety of system-on-chips (SoCs) or safety microcontroller units (MCUs) that require multiple low-dropout (LDO) regulators.

Five LDO linear regulators can provide up to 400mA of load current (ILOAD) per channel. Three independent voltage inputs allow different input voltage (VIN) levels to optimize dropout for their respective outputs. Four GPIO pins are available to be used for power sequencing, and two voltage monitors (including one differential monitor) monitor two external voltage rails.

Protection features include under-voltage lockout (UVLO), over-current protection (OCP), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown.

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

The I2C interface with packet error checking (PEC) and integrated one-time programmable (OTP) memory allow for configurability.

The MPQ70700FS-AEC1 is available in a TQFN-24 (5mmx5mm) package, and is available in AEC-Q100 Grade 1.
