STMicroelectronics STC4054GR Environmental and export classification status description
The STC4054GR is a linear battery charger designed for lithium-ion batteries using a constant current/constant voltage (CC/CV) charging algorithm. It features a built-in thermal regulation system that protects the device from overheating while charging. This IC is suitable for applications where low power consumption and simplicity in design are desired. Functions 1. Battery Charging: The main function is to charge lithium-ion batteries safely and efficiently. 2. Thermal Regulation: It automatically reduces the charging current when the die temperature exceeds a certain threshold. 3. Constant Current/Constant Voltage Charging: Implements a CC/CV charging method to ensure that batteries are charged effectively without overcharging. 4. Status Indicators: Provides status outputs to indicate the charging phase. 5. Input Voltage Protection: Protects against unwanted voltage that exceeds the specified limits. Applications - Smartphones: Used in mobile phones to manage battery charging. - Tablets: Applied in tablet PCs for efficient battery management. - Portable Devices: Designed for portable electronics such as cameras, handheld devices, and IoT devices. - Battery-Powered Tools: Suitable for tools and devices that require rechargeable battery systems. - Backup Battery Systems: Can be integrated into systems that use backup batteries. Alternative Parts While the STC4054GR is a versatile choice for battery charging, there are alternative parts within the STMicroelectronics portfolio and other manufacturers that serve similar functions: - STC4056: Another linear battery charger that can be used for lithium-ion batteries but may have slightly different specifications. - TP4056 from TPQ Technology: A popular Chinese alternative for lithium-ion battery charging applications. - MCP73831 from Microchip Technology: A linear battery charger IC suitable for simple charging applications. Embedded Modules Various modules incorporate the STC4054GR, making it simpler to use in prototype or product designs: - Battery Charger Modules: Boards that combine the STC4054GR with necessary passive components for easy integration into designs. - Evaluation Boards: Available for testing and design verification, including the necessary connectors, capacitors, and other components. - Development Kits: Kits that provide tools for engineers to assess and prototype designs using STC4054GR. Q&A 1. Q: What type of batteries can the STC4054GR charge? A: The STC4054GR is specifically designed to charge lithium-ion and lithium-polymer batteries using a constant current/constant voltage (CC/CV) algorithm. 2. Q: What happens if the temperature of the STC4054GR exceeds its limit? A: The STC4054GR has built-in thermal regulation that reduces the charging current if the chip temperature exceeds a predefined threshold to prevent overheating. 3. Q: Can I use STC4054GR for charging multiple batteries in parallel? A: While the STC4054GR is designed for charging single-cell batteries, using multiple ICs for parallel charging of separate cells is possible with appropriate current sharing design. 4. Q: What is the input voltage range for the STC4054GR? A: The STC4054GR typically accepts an input voltage range from 4.5V to 8V, which is suitable for USB and other common power sources. 5. Q: Are there ready-to-use modules for STC4054GR? A: Yes, there are several battery charger modules and evaluation boards available that integrate the STC4054GR for ease of use in projects and prototypes.
