HDK

  • KEY = flashing LED output and key function as below

Push button’s connecting is shown in Fig 5. IP5306 can identify long push and short push.

Feature Description
No Key Required If no key is needed, PIN5 can remain floating.
Short Press (30ms - 2s) Activates the battery level indicator and boost output.
Long Press (>2s) Turns the LED light on or off.
Press Duration (<30ms) No response will be triggered.
Double Short Press (within 1s) Turns off the boost output, battery level indicator, and LED light.

Typical SCH

versions

  • IP5306-I2C
  • IP5306-LC
  • IP5306 = 4.20V
  • IP5306_4.30V = 4.30V
  • IP5306_4.35V = 4.35V
  • IP5306_4.40V = 4.40V

Note

  • According to the data sheet (in Chinese language only by the way), if the load current drops below 45mA during 32 seconds, the IP5306 goes into standby.
  • battery need to be attached and "activate" by charging first
  • MAKE SURE to use high quality, full charged battery for testing, otherwise could cause power off
  • The board does not supports modern quick charging options, like QC, PD, etc

  • to prevent board enter into sleep mode automatically for small power load, you can add some more load resistors to keep it continuously on.

  • this chip has two version: LED version or I2C version, normllay we only provide LED-version

standby issue

  • You can use IP5306_CK，this version always output 5V.
  • I2C function only apply to IP5306_I2C custom design. you can order samples use the name: IP5306_I2C.
  • Accessory is the I2C register document of IP5306, you can use IP5306_I2C, then modify IP5306's register(reg0x00[1]=1) to make IP5306 always output 5V.
