1 OVERVIEW
The RK808 is a complete power supply solution for Portable systems. The highly integrated device includes four buck DC-DC converters, eight high performance ldos, two low Rds switches, I2C interface, programmable power sequencing and an RTC. The RK808 improves performance, reduces component count and size, and therefore provides lower cost solution compared to conventional portable designs. The ultra fast 2MHz current mode DC/DC architecture optimizes the transient performance and is compatible with tiny low co st ceramic inductors and capacitors. All DC/DC channels include integrated MOSFETS. Internal soft -start and compensation circuits minimize external components count. Most outputs can be programmed through the I2C interface

POWER ON disabled Sleep enabled Sleep disabled POWER ON disabled Figure 9-1 State Machine
9.2 DEVICE POWER-ON ENABLE CONDITIONS
If none of the device power-on disable conditions is met, the following conditions are available to turn on and/or maintain the ON state of the device:
- PWRON signal low level.
- Or interrupt flag active (INT low) while the device is off (NRESPWRON = 0) The power-on enable condition occurs only if the interrupt status bit is initially low (no previous identical interrupt pending in the status register). The Interrupt sources expected when the device is off are:
- PWRON low-level interrupt (PWRON_INT = 1 in INT_STS_REG1 register)
- First VDC rising above plug -in threshold (PLUG_IN interrupt(PLUG_IN_INT=1 in INT_STS_REG2 register) (Charger plug in interrupt) The Interrupt source expected if enabled when the device is off is:
- RTC Alarm interrupt (INT_ALARM_EN =1 in RTC_INT_REG and RTC_ALARM_I NT = 1 in INT_STS_REG register)

PWRON falling edge 2. RTC_ALARM_INT=1(if RTC_ALARM_INT_IM=0) or PLUG_IN_INT=1(if PLUG_IN_INT_IM=0) when NRESPWRON=0 POWER OFF: 1. DEV_OFF_RST=1 2. DEV_OFF=1 3. 2s delay after PWRON_LP_INT=1 4. VB_UV=1 5. TSD=1 6. VB_LO_STS=1 and if VB_LO_ACT=0 Figure 9-2 Power On Enable Control
9.3 DEVICE POWER-ON DISABLE CONDITIONS
- PWRON signal low level during more than the long-press delay: TDPWRONLP. The interrupt corresponding to this condition is PWRON_LP_INT in the INT_STS_REG register.
- Or Die temperature has reached the thermal shutdown threshold : TSD_STS=1 in THERMAL_REG).
- Or Vbat down below UVLO threshold: VB_UV_STS=1 in VB_MON_REG.
- Or DEV_OFF or DEV_OFF_RST control bit set to 1 (value of DEV_OFF is cleared when the device is in OFF state).
9.4 DEVICE SLEEP ENABLE CONDITIONS
- SLEEP signal high level.
- OR DEV_SLP control bit set to 1
- And interrupt flag inactive (INT high): No non-masked interrupt pending The SLEEP state can be controlled by programming DEV_SLP and keeping the SLEEP state.
