Auto detection on sink device/phone attachment

IP5328P support auto detection on sink device/phone attachment/ plug in, once the attachment is detected,

the boost will be turned on charging the sink device/phone, so non-key solution are supported.

Auto detection on sink device/phone fully charged

IP5328P detect the current output current through off-chip 10mOhm resistor, when the total power is lower

than 300mW for 32s, IP5328P will consider all the output port is plug out, the output voltage will be closed then.

Key circuit

Key circuit is illustrated in Figure 3, which can recognize short press or long press operation.



Short press (pressed time in range of 60ms~2s): turn on the battery level display LED and BOOST

output



Long press (pressed time longer than 2s): turn on or turn off the torch light WLED



No response on press time less than 30ms



Two short press in 1s: turn off boost output, battery level display LED and torch light WLED



Long 10s press will reset the whole system

Fast Charge state indication

Light is used for indication for the present fast charge mode, either in fast charging or discharging mode,

when the system enters fast charge mode and in non-5V mode, the light LED will turn on.
