Introduction
The bq2477x is a high-efficiency synchronous NVDC-1 battery charging controller with a small number of components, suitable for multi-chemistry battery charging solutions in space-constrained applications. Power path management can stabilize the system voltage at the battery voltage, but not lower than the minimum system voltage (programmable). With this function, the system can keep running even when the battery is fully discharged or removed. Thanks to power path management, the battery can provide supplementary current to the system to prevent the input power supply from overloading. The bq2477x provides drivers and power path management for N-channel ACFETs and reverse-blocking FETs. The device also provides corresponding drivers to control the NVDC operation of external P-channel battery FETs. It can also drive the high-side and low-side metal-oxide-semiconductor field-effect transistors (MOSFETs) of the switching regulator. The bq2477x can monitor the adapter current (IADP), battery charge/discharge current (IBAT), and system power (PMON). The device also features a flexibly programmable PROCHOT output that can directly control the CPU to reduce its operating speed as needed.
