The BQ25640 is a highly-integrated 5A switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer batteries. The design is highly integrated with built-in current sensing, loop compensation, input reverse-blocking FET (Q1), switching FETs (Q2 and Q3), and battery FET (Q4) between system and battery. The device integrates a USB Type-C controller with Dual-Role Power with Try.SNK and Try.SRC support. The BQ25640 uses NVDC power path management, regulating the system slightly above the battery voltage without dropping below a configurable minimum system voltage. The low impedance power path optimizes efficiency, reduces battery charging time and extends battery life during discharging phase, and the ultra-low 0.15µA ship mode current extends battery shelf life.
