YD7388 datasheet

Description

This is 25W four-channel (BTL) audio amplifier circuit. The YD7388 is a class AB Audio Power Amplifier. It allows a rail to rail output voltage swing with no need of bootstrap capacitors for the fully complementary PNP/NPN output configuration.  The YD-7388 is suitable for high end car radio applications.

The circuit characteristics are as follows:

Output power: Po = 25W × 4 (Vcc = 14.4V, BTL, RL = 4Ω, THD = 10%);

Four-channel BTL circuits are used, no external output capacitor, Using HZIP25B power package.

IP5306 Datasheet

Description

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

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

Applications

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.
