Data sheet:
Certificate:
The BQ25690 is a fully integrated switch-mode buck-boost charger for 1- to 7 cell Li-ion batteries, Li-polymer batteries. Wide input voltage range from 2.5V to 36V supports applications powered from battery, standard USB-PD adapters and high voltage dedicated DC adapters. The device integrates 4 switching MOSFETs and all the converter loop compensation for small solution size with simple design. It uses NVDC power path management, regulating the system slightly above the battery voltage without dropping below a configurable minimum system voltage. When system power exceeds the input source rating, battery supplement mode supports the system without overloading the input source. The device also supports the full input (sink) and output (reverse or source mode) voltage ranges for USB Type-C and USB power delivery (USB-PD) applications.
- High integration buck-boost forward (sink) mode charger for 1- to 7-cell Li-Ion batteries supporting USB PD profile with integrated switching MOSFETs and loop compensation
- Highly efficient
- Programmable switching frequency from 450kHz to 1.2MHz
- Bypass mode for >98.5% efficiency USB-PD PPS direct battery charging at 20V, 3A
- Selectable PFM with out-of-audio (OOA) operation for light load efficiency improvement
- Supports a wide range of input sources with 2.5V to 36V operating range and 45V absolute maximum rating
- Support VIN down to 2.5V with VBAT > 3.2V
- USB-PD input
- Input voltage dynamic power management (VINDPM) up to 36V to prevent input source overload
- Optional input current dynamic power management (IINDPM) up-to 3.3A for maximum power limit
- Optional Narrow voltage DC (NVDC) power path management
- System instant-on with depleted or no battery
- Battery supplements system when the adapter is fully loaded
- I2C controlled for optimal system performance with resistor-programmable option
- Hardware selectable default cell count, charge voltage, input and charge current limits
- 3A charging current with 20mA resolution
- Reverse/OTG (source) mode powers input port from battery
- 3.5V to 34V reverse output voltage with 20mV resolution to support USB-PD PPS
- Up-to 3.3A reverse output current regulation with 20mA resolution to support USB-PD PPS
- Low quiescent current
