IP5306 Datasheet


The IP5306 is a multi-function power management SOC with an integrated boost converter, lithium battery charge management, and battery power indication, providing a complete power solution for mobile power supplies.
The high integration and rich features of the IP5306 make it possible to use only a few external components in the application and to effectively reduce the overall solution size and BOM cost.

Features for IP5306

1. Synchronous switch charge and discharge
2. 2.4A Synchronous Boost Converter, 2.1A Synchronous Switch Charge
3. Boost efficiency up to 92%
4. Up to 91% charge efficiency


1. Mobile Power / Charging Po
2. Mobile phones, tablet PCs and other portable devices




Key method

The IP5306 recognizes long and short key operation, and pin 5 is floating when no key is needed.

1. The key duration is longer than 50ms, but less than 2s, which is a short press action. Short press will turn on the power indicator and boost output.

2. The duration of the button is longer than 2 seconds, which means long press action. Long press will turn on or off the lighting LED.

3. The keystrokes less than 50ms will not have any response.

4. Pressing the button for two consecutive times in 1s will turn off the boost output, battery display, and lighting LED.

74AC245 datasheet



The 74AC245 octal bus transceivers are designed for asynchronous two-way communication
between data buses. The control-function implementation minimizes external timing
requirements. When the output-enable (OE) is low, the device passes noninverted data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input.

A high on (OE) disables the device so that the buses are effectively isolated.
To ensure the high-impedance state during power up or power down, OEshould be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.


1. 2-V to 6-V VccOperation
2. Inputs Accept Voltages to 6 V
3. Max tpd of 7 ns at 5 V
