4.8 Power Management Unit (PMU)
PMU consists of DC-DC converter, regulator and battery monitor.
In ATJ2085, there are two DC/DC converters and one liner regulator. One DC/DC converter is for
VCC power supply and another is for VDD. The liner regulator is for VDD power supply when two
battery mode or other conditions where need less external components.
In ATJ2085, the default value of VCC is 3.0V and VDD is 2.0V. The regulator’s default output is
2.0V; all three values can be controlled by Registers. The VCC is from 2.8V to 3.3V; VDD is from
1.6V to 2.3V; the regulator is the same as VDD.
ATJ2085 supports one-battery mode, two-battery mode, USB power supply or DC power line-in.
