TP5600

The TP5600 is a powerful, highly integrated circuit primarily used in mobile power supplies. It integrates five major functions into a single chip: multiple protections (including reverse input power protection), automatic charging management, automatic boost voltage management, battery level display, and battery protection. It boasts powerful functionality yet requires simple external circuitry, offering stable and reliable performance, making it ideal for mass production with minimal debugging and high efficiency and yield. The TP5600 utilizes a unique single inductor reuse technology, incorporating a highly efficient synchronous buck 4.2V 2A lithium battery charging circuit and a synchronous boost 5V 2A output circuit; a 4-way LED display output allows for 5-segment indication of charging and discharging levels, directly driving red, green, and blue LEDs, and also serving as an abnormal status alarm; no external battery protection circuit is needed, as it integrates multiple input and output protections (overvoltage, overcharge, undervoltage, overcurrent, short circuit, etc.). The TP5600 specifically integrates reverse input power protection to prevent lithium battery damage and combustion caused by accidental reverse power connection during production, maintenance, or user connection. The TP5600 offers simple external circuitry options for customers to choose different functions and performance: such as whether to automatically switch to boost mode when the charging input power fails; automatic shutdown under light load (during boost); adjustment of buck charging constant current; adjustment of 5V boost output maximum current limit. The TP5600 incorporates an adapter power adaptive circuit. When the VIN current drive is insufficient, causing VIN to drop to 4.2V, the internal circuit automatically reduces the charging current to adapt to different power USB ports, power supplies, or adapters. The TP5600 integrates reverse protection PMOSFET1 and anti-backflow PMOSFET2 circuits, eliminating the need for external diodes for reverse protection, and can withstand a maximum reverse input voltage of -10V.
