100W fast charging power bank (0.91' OLED screen)

100W fast charging power bank (0.91'OLED Screen)

Overview

A 100W fast-charging mobile power supply based on the IP5389 chip solution, equipped with an OLED display that can display battery power and temperature, charge and discharge voltage and current; capacitive touch key switch with lighting. Main features: - Using IP5389_I2C_AACC fast charging chip, which can realize PD two-way 100W fast charging - 4 high-rate 18650 batteries, integrated battery protection and balancing chip, with NTC high temperature protection - Integrated STM8S103 microcontroller and 0.91-inch OLED display, which can Display battery power and temperature, charge and discharge voltage and current - Capacitive touch button with touch indicator light - With 0.2W lighting - After the mobile power supply is automatically turned off, the microcontroller will also enter shutdown mode. According to the official manual, there is 30uA; the touch chip standby power consumption is only 1.5uA; the standby power consumption of the 0.91-inch OLED screen is only a dozen uA.

Methods for reducing board size and battery consumption in low voltage H-bridge applications
There are several approaches to designing low-voltage systems in motor-driven building automation and grid infrastructure applications such as smart meters, smart locks, Internet Protocol (IP) network
When the LSM6DS3TR-C is configured with the I2C address, the power consumption is high when the SA0 pin is connected to GND.
Hello everyone, when the LSM6DS3TR-C is configured in the I2C address, when the SA0 pin is connected to GND, there is a 10k pull-down resistor. The power consumption will increase by 0.5mA compared to
