General Description

The RT2070T is a highly-integrated low-power highperformance

analog SOC with PMIC (Power Management

IC) in one single chip designed for Industrial/Automotive

applications.

The RT2070T PMIC includes one high voltage synchronous

step-down DC-DC converter, two low voltage synchronous

step-down DC-DC converters, one low dropout LDO and

one load switch with soft-start control and current limit.

All MOSFETs are integrated, and compensation networks

are built-in.

The RT2070T also uses I2C interface to set timing of power

on/off, sequence and discharge function, and includes

power good indicator (PGOOD).

The RT2070T is an Automotive-Grade Product that is

AEC-Q100 Grade 1 Qualified and provides fault condition

protections, including over-current protection, undervoltage

lockout, over-voltage protection and overtemperature

protection.
