Datasheet
● Reset
There are two kinds of reset, software reset and hardware reset
(1)Software reset
? All the registers are initialized by SFTRST="1".
? SFTRST is an automatically returned to "0". (Auto Return 0).
(2) Hardware reset
? It shifts to hardware reset by changing RESETB pin “H” → “L”.
? The condition of all the registers under hardware reset pin is returned to the Initial Value, and it stops accepting all address.
? It’s possible to release from a state of hardware reset by changing RESETB pin “L” → “H”.
? RESETB pin has delay circuit. It doesn’t recognize as hardware reset in “L” period under 5 μ s.
(3) Reset Sequence
? When hardware reset was done during software reset, software reset is canceled when hardware reset is canceled.
(Because the Initial Value of software reset is “0”)
● VIODET
The decline of the VIO voltage is detected, and faulty operation inside the IC is prevented by giving resetting to Levelsift block

When the VIO voltage becomes more than typ1.0V(Vth of NMOS in the IC), VIODET is removed.
On the contrary, when VIO is as follows 1.0V, it takes reset.(The VBAT voltage being a prescribed movement range)
● Thermal Shut Down
A thermal shutdown function is effective in the following block.
DC/DC (Charge Pump)
LED Driver
SBIAS
LDO1, LDO2, LDO3, LDO4
The thermal shutdown function is detection temperature that it works is about 195 ℃ .
Detection temperature has a hysteresis, and detection release temperature is about 175 o C.
