The high input voltage – 10% Charge Current Accuracy range with input overvoltage protection supports low- cost unregulated adapters. – Supports Applications for Very Low Charge Currents - 10 mA to 250 mA The bq2510x has a single power output that charges the battery. A system load can be placed in parallel – Supports minimum 1-mA Charge Termination with the battery as long as the average system load Current does not keep the battery from charging fully during – Ultra Low Battery Output Leakage Current - the 10 hour safety timer. Maximum 75 nA The battery is charged in three phases: conditioning, – Adjustable Termination and Precharge constant current and constant voltage. In all charge Threshold phases, an internal control loop monitors the IC – High voltage Chemistry Support: 4.35 V with junction temperature and reduces the charge current bq25100H/01H, 4.30 V with bq25100A if an internal temperature threshold is exceeded. • Protection The charger power stage and charge current sense – 30-V Input Rating; with 6.5-V Input functions are fully integrated. The charger function Overvoltage Protection has high accuracy current and voltage regulation loops and charge termination. The pre-charge current – Input Voltage Dynamic Power Management and termination current threshold are programmed – 125°C Thermal Regulation; 150°C Thermal via an external resistor on the bq2510x. The fast Shutdown Protection charge current value is also programmable via an – OUT Short-Circuit Protection and ISET Short external resistor.
