An accurate and fast comparator monitors the

over-voltage condition of the input. If the input

voltage rises above the threshold, the input-to-

ground discharge path is active. When the input

voltage falls below 5.5V (typical), the MP5034

exits OVP mode.

The input-to-ground discharge resistance is

always active during the high-to-low voltage

mode change period. The discharge path is

turned off when FB becomes less than 108% *

auto-detect

function,

which

recognizes most mainstream portable devices.

The MP5034 supports the following charging

schemes:

 USB battery charging specification BC1.2/

Chinese

Telecommunications

Industry

Standard YD/T 1591-2009

 Divider mode

 1.2V/1.2V mode

 Qualcomm quick-charge mode 3.0 and 2.0

Thermal Shutdown

Thermal shutdown prevents the chip from

operating at exceedingly high temperatures.

When the silicon die temperature exceeds

160°C, the entire chip shuts down. When the

temperature falls below its lower threshold

(typically 125°C), the chip is enabled again.
