ESD Warning
The IDTP95020 is an ESD (electrostatic discharge)
sensitive device. The human body and test equipment
can accumulate and discharge electrostatic charges up to
4000 Volts without detection.
Even though the
IDTP95020 implements internal ESD protection circuitry,
proper ESD precautions should be followed to avoid
damaging the functionality or performance.

Sleep
USB or AC Adaptor is not present, a main battery is present and
well-charged. Always on LDO_LP is on, RTC is on and RTC
registers are maintained. Wake-up capabilities (Switch Detect Input)
are available.
VBAT = 3.8V
85 * 3.8 = 323 W
Standby
USB or AC Adaptor is not present, a main battery is present and
well-charged. Always on LDO_LP is on, all DC-DC Bucks in PFM
mode. All LDOs are on, no load.
VBAT = 3.8V
385 * 3.8 = 1463 W
Touch Controller
Standby
USB or AC Adaptor is not present, a main battery is present and
well-charged. Always on LDO_LP is on, touch screen controller is
on, LDO_050_0 is on.
VBAT = 3.8V
7.4 * 3.8 = 28.12 mW
