Power States
The IDTP95020 device has two hardware power states.
OFF State
The IDTP95020 enters the OFF state after the first time battery insertion. The system power (VSYS ) is provided by the battery
via the ideal diode when VSYS powers-up, it will issue a power-on-reset to reset all the logic on the device to the default state
and the IDTP95020 enters the OFF state. In this state:
-
The 32K crystal oscillator (or associate RC oscillator) is running and generates 32k/4k/1k clocks.
-
The RTC module is enabled and the RTC registers are maintained.
-
The always-on LDO is enabled and provides power to the system.
-
The power switch detection (SW_DET) circuit is running.
-
The Ideal diode driver is running.
-
All regulators, touch screen controller and audio are in power down or inactive mode.
-
Wait-for-interrupts is active (Short button push or adapter insertion) to wake up CPU and bring system to ON state.
