Зарядные ИС для аккумуляторов BQ24075TRGTT

Зарядное устройство для 1-элементной литий-ионной батареи , 6.4В вход, 4.2В/1.5A зарядка, QFN-16

The BQ24075TRGTT is an USB-friendly Li-ion battery charger and power-path management Integrated Circuit targeted at space-limited portable applications. This device operates from either an USB port or AC adapter and support charge currents up to 1.5A. The input voltage range with input over-voltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the BQ2407xT to meet USB-IF inrush current specification. Additionally, the input dynamic power management VIN - DPM prevents the charger from crashing incorrectly configure USB sources. The IC features dynamic power path management (DPPM) that powers the system while simultaneously and independently charging the battery. The DPPM circuit reduces the charge current when the input current limit causes the system output to fall to the DPPM threshold. Thus, supplying the system load at all times while monitoring the charge current separately.
