Introduction

AI Translation

The bq2510x series of devices are highly integrated lithium-ion and lithium-polymer linear chargers designed for space-constrained portable applications. The high input voltage range with input overvoltage protection supports low-cost, unregulated adapters. The bq2510x has a power output that can charge the battery. If the average system load cannot fully charge the battery within the 10-hour safety timer period, the system load can be connected in parallel with the battery. Battery charging goes through the following three stages: regulation, constant current, and constant voltage. During all charging stages, the internal control loop monitors the IC junction temperature. When it exceeds the internal temperature threshold, it reduces the charging current. Both the charger power stage and the charging current sensing function are fully integrated. This charger features high-precision current and voltage regulation loops and a charge termination function. The pre-charge current and termination current thresholds can be programmed via an external resistor on the bq2510x. The fast charge current value can also be programmed via an external resistor.
