The CW6305B is a high-accuracy linear charger IC with integrated power path management, designed for Wearables and IoT devices utilizing single-cell Li-ion/Li-Polymer batteries. It manages full charge phases, including pre-charge, constant current (CC), constant voltage (CV), and charge termination.
The device features power path management (PPM) that enables it to power the system while simultaneously charging the battery, even if the battery is depleted. It supports system reset and shipping mode, providing instant power-on functionality. The CW6305B offers system over-current protection (OCP) by limiting input and battery currents. It also includes battery NTC thermistor monitoring for temperature-based charging suspension and adjustable thermal regulation.
Additional features include a charge safety timer, pre-charge timer, and an I2C serial interface for host configuration and status monitoring, along with an I2C watchdog. The CW6305B is available in a compact, lead-free CSP-9 package.
Applications include Internet of Things devices, fitness accessories, smartwatches, BT headsets/TWS earbuds, and low-power handheld devices.
