Background of the programme
With the acceleration of people's lifestyle, the demand for portable electronic devices is increasing. Especially in the cold season, hand warmers have become an indispensable portable device for many people. Combining the functions of a mobile power bank and a hand warmer, it can effectively solve the needs of hand warmth and charging electronic devices when going out. The aim of this electronic solution is to develop a device that combines these two functions and is not only portable, but also versatile and meets the diverse needs of modern people.
Scenario features
Battery Operated:Powered by a high-efficiency battery, the long-lasting performance of the device is guaranteed.
Constant pressure scheme:Ensure that the power output is stable and provides safe and reliable power to the connected devices.
Main control chip:Using the DLTAP713SC from JLTech, this chip provides stable control to ensure the efficient and safe operation of the equipment.
Multi-functional interface:It is equipped with a mechanical button, a digital tube, an NTC (temperature controller), and a heating element for easy operation and temperature control.
Multi-mode heating:Three heating modes (40°C, 50°C, 60°C) are available to meet different temperature requirements.
Power display:The digital tube can display the current power level, so that the user can know the status of the device at any time.
Smart Charging & Hand Warmer Function:The power bank function and hand warmer function cannot be used at the same time to ensure safe use.
Advantages of the solution
Portability:Combine the dual functions of a power bank and a hand warmer to reduce the burden of carrying.
Intelligent control: Through one-button operation, it is easy to switch between the on/off state and the heating mode, which is user-friendly.
High security:Below 30V automatic shutdown function to prevent over-discharge of the battery.
Charging efficiency:When charging, the digital tube dynamically displays the power level in a 0-100% manner, allowing users to clearly understand the charging status.
Environmental protection and energy saving:There is no memory function, reducing energy consumption and extending the life of the equipment at the same time.
Low-power design:The low-power design of the battery product improves the efficiency and battery life of the device.
Solution implementation details
Power-on and power-off: When powering on for the first time, it will be in the shutdown state by default, and the digital tube will enter the standby state after 2 seconds of lighting.
Key Function:
Press and hold for 2 seconds to power on and off:One-touch and long press to turn the device on or off.
Short press to switch heating mode: A simple short press to switch between different heating modes.
Temperature and battery level display: After short press, the digital tube will first display the selected temperature level for 5 seconds, and then display the battery level.
Power inquiry: Short press to check the battery level when the power is off, and double click to check the battery level when the power is on.
Charging status display:While charging, the digital tube displays the battery percentage and a flashing lightning sign, and the lightning sign stays on when fully charged.
