PMIC - Battery Chargers: SPV1050TTR application field and working principle

The SPV1050TTR is an integrated circuit (IC) from the PMIC - Battery Chargers family, with typical applications in charging Li-Ion (Lithium Ion) battery packs with up to 3 cells in series. It can also be used to charge unbalanced power sources through a balanced charging algorithm. It is able to handle up to 1.5A of charging current and can provide up to 10V of output voltage with ±2% accuracy.The SPV1050TTR working principle is relatively simple. It integrates two main functions, the constant current/constant voltage (CC/CV) charging protocol and the charge-cycle balancing algorithm. The former means that the voltage across the battery terminals is held at a constant level as the current goes through it, thus protecting the cells from overcharging. The latter feature, usually seen on Li-Ion battery packs, ensures an even charge distribution among the cells for improved battery life.The SPV1050TTR is designed for high temperature and high humidity environment, and has a wide operating temperature range from -40°C to +85°C. It also features low current consumption (less than 10µA) in idle mode and short-circuit protection.As for application fields, the SPV1050TTR is suitable for a variety of consumer and industrial applications, including consumer electronics and medical applications, where it can be used for charging Li-Ion battery packs with up to 3 cells in series, at a rate up to 1.5A. It can also be used in automotive applications where it can be used as an on-board charger.To sum up, the SPV1050TTR is an IC from the PMIC - Battery Chargers family, suitable for a variety of consumer and industrial applications. It integrates two main functions, the constant current/constant voltage (CC/CV) charging protocol and the charge-cycle balancing algorithm. It is able to handle up to 1.5A of charging current and can provide up to 10V of output voltage with ±2% accuracy. Moreover, it is designed for high temperature and high humidity environment, and has a wide operating temperature range from -40°C to +85°C.
