MT6370 is a highly integrated intelligent power management ICC, which includes a battery ion/polymer Switching battery charger, a USB type & power Delivery (PD) controller, dual flash diversion source, ARGB led driver, backlight driver, Displays bias drivers and general-purpose Ldo portable devices.
The switch charger integrates a synchronous PWM controller, power supply moss, input current sensing and input current regulation, high precision voltage regulation, and charging termination circuitry. In addition, the charge current is regulated by the integrated sensing resistor. The mt6370 also provides USB online support.

The USB type-C&PD controller complies with the latest USB type-C and PD standards. The mt6370 integrates a complete C-type transceiver including C-stop resistors, RP and Rd, and enables USB type-C detection including attachments and orientations. It is also an integrated USB BMC physical layer power supply protocol that allows for power transfer and role swapping. The BMC PD function provides an alternate member with full support for the USB type-C standard mode.
Dual independent current sources are available every time a flash is available. The power of the current in the frequency mode is derived from
Used to provide the charger in reverse drive mode, the same as the OTG mode operation of the charger. I do not know. High-side current source, allows the grounding cathode to connect to the LEDs, and provides a strobe mode current level from 25ma

At 12.5 horse or from 25 Ma to 1.5a750ma in 6.25ma step and torch mode current level from 25ma to 400ma12.5 horse. These two channels can support a total reach of 2.5 degrees.
The backlight-rotated driver supports up to 8 Series 4 channels of 29v output voltage wleds. Each channel supports up to 30ma of existing capabilities, with existing 2048-step exponential or linear mapping curves. I don't know. Backlight brightness is controlled by the I²c control interface and the external PWM control. I do not know. The PWM frequency range is 50hz to 50khz. MT6370 can also support the Torc/strobe adjustment constant in the backlight mode of the current front camera screen flash application.

Implemented a display bias driver (db) with a single inductor booster and an inverting charge pump reaching a smaller PCB area, compared to a dual inductor booster converter. The display bias driver is used to provide a negative voltage out (Vdb_neg) through the db_negvout pin and a positive voltage output (Vdb_pos) This is a very important issue. The negative voltage output comes from the boost converter output voltage (VDB_BST) at the db_bstvout pin, and the positive voltage output is from the db_posvout voltage through a I want to reduce the power noise. The Vdb_pos and Vdb_neg voltage range can be from 4 kv to 6 volts, from 4 kv to -6v, with resolutions of 50MV respectively. These two input xxx, usually connected to the source driver IC, can support up to 50ma output current drive capacity up to ten "TFT-LCD panel.

The RGB LED driver is a 4 channel intelligent leader String controller that drives 3 channels of LED with up to 24ma sink current with a high power indicator current of up to 6ma. All channels can be set independently via the I²c interface and are available in three modes of operation: scratchpad mode, PWM mode and breathing mode. mt6370 can use 4.22 x4.32 (BSC) package in wl-cps-93b
