STC4054GR IC BATT CHRGR 800MA TSOT23-5

The STC4054GR is a compact and efficient linear battery charger IC designed for single-cell lithium-ion batteries. Housed in a tiny TSOT23-5 package, this IC is ideal for portable devices where space is at a premium. With a charging current of up to 800mA, the STC4054GR provides a fast and reliable charging solution for smartphones, wearables, and other battery-powered electronics. Its integrated features, such as thermal regulation and reverse blocking protection, ensure safe and reliable operation. The STC4054GR simplifies battery charging circuit design, reducing the number of external components required and minimizing board space.

The STC4054GR utilizes a constant-current/constant-voltage (CC/CV) charging algorithm, which is the industry standard for lithium-ion battery charging. During the constant-current phase, the IC delivers a fixed current to the battery until it reaches its target voltage (typically 4.2V). Then, the IC switches to the constant-voltage phase, maintaining the voltage at 4.2V while gradually reducing the charging current. This ensures that the battery is fully charged without being overcharged or damaged. The STC4054GR also features a pre-charge mode for deeply discharged batteries, gently charging them at a lower current until they reach a safe voltage level.

The STC4054GR incorporates several protection features to ensure safe and reliable battery charging. Thermal regulation prevents the IC from overheating by reducing the charging current when the junction temperature exceeds a certain threshold. Reverse blocking protection prevents current from flowing back into the IC from the battery, protecting the IC from damage in case of accidental reverse voltage connection. The STC4054GR also features a charge status output, which can be used to indicate the charging status of the battery. This output can be connected to an LED or a microcontroller to provide visual or digital feedback to the user.

Consider the STC4054GR for your next project requiring efficient and reliable lithium-ion battery charging. Its compact size, high charging current, and integrated protection features make it an ideal solution for portable devices. Whether you're building a smartphone, a wearable, or a handheld electronic device, the STC4054GR offers the performance and flexibility you need.
