bq25185 + TPS61023 = USB or Solar lipoly with 5V output 🔋☀️🔌

We spent the weekend tweaking our bq25185

https://www.digikey.com/short/8hd2778w

designs and made one basic breakout for this flexible battery charging chip. Then, we made a board with a 3.3V buck output to charge the battery with a USB or solar panel and got a clean and consistent 3.3V out. With both of those working, here's a design for a version that has a 5V booster with the TPS61023

, which gives a nice clean 1A with a small bill of materials. Now you can use USB, DC, or solar to charge your favorite lipoly or liion chip and get 5V output. Maybe we'll make a version that can handle 3.6V LiFePO4 batteries, too? It's easy to set the bq to handle those by changing a single resistor.

Bluetooth Chip PHY6222 Application in Laifen Electric Toothbrush: Details, Reasons for Selection, and Alternatives

I. Introduction

Recently, the electric toothbrush product to be launched by the Chinese manufacturer Laifen has caught my attention.

As a loyal fan of Laifen, I highly appreciate this brand. Although its high - speed hair dryer may seem to be imitating Dyson, it has actually promoted the overall optimization of the Chinese hair dryer industry. Consumers can get a much - better - performing product with a slightly higher cost.

The brand's marketing approach, technology - sharing culture, and accurate identification of product pain points are all worthy of in - depth study.

I'm looking forward to the electric toothbrush launched at Laifen's official press conference. I will definitely buy it for experience once it's on the market. Even if it might be considered as paying an "IQ tax", I'm willing to give it a try.

As an engineer, I'm more concerned about the Bluetooth chip used in this product.

Although I think adding Bluetooth functionality to an electric toothbrush has little practical significance as consumers usually only use it to connect to the app for parameter settings once and rarely connect again, the manufacturer must have its own considerations.

PHY6222 Bluetooth Chip

The PHY6222 is a System - on - Chip (SoC) that supports BLE 5.2 functionality and the IEEE 802.15.4 communication protocol. It integrates an ultra - low - power high - performance multi - mode radio transceiver, is equipped with a 32 - bit ARM®Cortex™ - M0 processor, and provides 64K retention SRAM, optional 128K - 8M Flash, 96KB ROM, and 256 - bit efuse. It supports security architectures, applications, and OTA online upgrades based on BLE and IEEE 802.15.4. In addition, the chip's serial peripheral IO and integrated application program IP help customers develop their products with the minimum BOM cost.

It adopts a standard QFN32 package.

Guesses on Why Laifen Chose PHY6222

Recommended by the Solution Company: The PHY6222 has good performance, but its cost is relatively high.

Platform Access Considerations: When designing the solution, they considered accessing systems such as mesh, Tmall, and Mi Home. Since the PHY6222 had already been integrated into these platforms, they initially chose this chip, although they later gave up and developed their own platform app.

Project Planning Factors: When planning the project two years ago, considering performance, cost, and power consumption comprehensively, the PHY6222 was the most suitable chip, so they chose it.

Recommended by the Manufacturer: However, this possibility is relatively small because they were a small manufacturer at the beginning, and it was difficult for the manufacturer to foresee their development potential.

Final Recommendation

From the current perspective, the main purpose of adding Bluetooth functionality to an electric toothbrush is to connect the interaction between the mobile phone and the toothbrush. Therefore, when choosing a chip, the following aspects should be focused on:

Power Consumption: The Bluetooth part of the toothbrush needs to broadcast continuously, so high power consumption is not acceptable.

Cost: Cost control is always crucial for consumer products.

Cooperative Relationship: The original supplier system is usually given priority. Even if the cost is slightly higher, as long as the service is good, it's acceptable.

Based on this, we highly recommend the KT6368A dual - mode Bluetooth chip, which adopts an SOP8 package. The KT6368A chip supports dual - mode Bluetooth and is of Bluetooth 5.1 version. Its highlights include ultra - small size, affordable price, and simple and clear transparent transmission and serial port AT control functions, which greatly reduce the development difficulty and cost of embedding Bluetooth in other products.

This chip is a low - power version, and its average power consumption can be controlled at around 200uA.

PCM510x MCLK-less I2S DAC with line level out 🎧💻

We're starting to stock a lot of chips that are able to do digital I2S out, which makes for great-quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real-time. However, we could really use some better DACs in the shop. We like the UDA1334A

..., but that's technically discontinued - it's great because it doesn't require an MCLK that some boards like the Raspberry Pi don't have and doesn't need I2C configuration either. The PCM510x is a good family, too; it ranges from the inexpensive PCM5100 (https://www.digikey.com/short/z50cnp0h) to the PCM5102 (https://www.digikey.com/short/80z2nh3h) which has high quality output at a higher cost. This breakout could use any of the family chips & gives you all the GPIO needed with a 3.5mm headphone jack for line-level output.

For example, when the "Store" button is pressed, the chip immediately broadcasts "Please select an available cabinet." When the "Pick up" button is pressed, it prompts "Please enter the pickup code." This guides users to complete the operation through voice, reducing the complexity of operation.

Sensor - triggered Mode：With the help of the sensors built into the locker, intelligent voice interaction is achieved. When a user approaches the locker, the human infrared sensor detects the signal, and the chip automatically plays the welcome message "Welcome to use XX shared lockers." When the cabinet door is opened or closed, the door magnetic sensor triggers the chip to broadcast prompts such as "The cabinet door has been opened. Please store or retrieve items." and "The cabinet door has been closed. Please leave with peace of mind." providing users with timely and considerate voice feedback.

Remote Control Mode：By connecting to the cloud management system, the KT148A chip supports remote voice content update and function upgrade. Enterprises can remotely modify voice prompt contents according to operational needs, release promotional activity information, safety notices, etc. When the system detects a locker failure, it can also remotely control the chip to broadcast fault prompts, guiding users to contact customer service for handling, achieving intelligent and efficient management.
