CONFIDENTIAL B
27
Charger: Pre-Charge Pre-Charge 1. 2.
When VPREC (default=3V) > VBAT > 2V, the charging current will increase to pre-charge current (default = 150mA) level which set by register. For system boot up consideration, VSYS will be regulated by system minimum level (default = 3.6V) which can be programmed by I2C
CONFIDENTIAL B
28
Charger: Constant Current Fast Charge 1. 2.
After VBAT > VPREC (default = 3V), the charging current will decided by main charging factor. The charging current is programmable from 0.3 to 3A. (default = 2A)

Analog IR Drop Compensation
▪ IR Compensation 1. 2. 3. 4.
Compensate the resistance of MT6360 to battery connector path The IR compensation can speed up the total charging time In order to protect battery, MT6360 features Battery OVP function. OVP level is decided by VOREG*108% After trigger BATOVP, charger will stop charging battery but power path keeps turn on for system loading. VBAT (Comp)

RGB: Application Circuit It is a three-channel LED driver designed to produce variety of lighting effects for mobile device. The device is gradually increase or decrease the brightness of the backlight LED upon command by I2C control, and it also can support RGB mode to select PWM mode, Breath mode and Register mode. The RGB_ISINK1 default setting is auto mode that using for TA charging indicator, It also support to software mode. For the RGB application, user must consider the LED forward voltage, the MT6360 RGB current sink headroom and the minimum battery application voltage to make sure the output current accuracy.
Note: To do RGB register setting before enable.

RGB: PWM Mode The MT6360 features a built-in PWM mode control by setting ISINKx_DIM_MODE to 00. The RGB_ISINK1~RGB_ISINK3 of the MT6360 can provide up to 24 mA per string. There are 13 step LED current control by setting ISINKx_CUR_SEL each channel. The ON/OFF of the current source is synchronized to the PWM signal. The frequency of LED current is equal to the PWM input signal that is setting by ISINKx_DIM_FSEL. In order to guarantee the PWM resolution, the PWM frequency have to be operated at range of 0.1Hz to 256Hz that is selected by ISINKx_DIM_FSEL.

RGB: Breath Mode In the breath mode, the 3 channels of the MT6360 can provide up to 24 mA per string. There are 13 step LED current control by setting register ISINKx_CUR_SEL each channel. In order to provide a smooth breath mode, there are 6 period timing to control the rising time and falling time, and it is control by setting register ISINKx_VREATH_TON_SEL, ISINKx_BREATH_TOFF_SEL, ISINKx_BREATH_Trx_SEL and ISINKx_BREATH_Tfx_SEL. In breath mode, the sink current work like PWM output with 256Hz and control the duty to similar the breath up and down.
