TI Intros 30V Linear Battery Chargers with Automatic USB Detection

Texas Instruments Inc. (TI) has introduced two families of 0.8A USB battery chargers with automatic USB detection for single-cell, lithium-ion (Li-ion) battery-powered electronics. The BQ2404x and BQ2405x battery charger integrated circuits have a high input-voltage range of up to 30V, and 6.6V overvoltage protection to support handheld devices, from entry-level feature phones to smartphones, and other low-power handheld devices, that may use low-cost adapters.

The BQ2405x’s automatic USB detection feature can intelligently detect if a power source is a dedicated power adapter or USB port. This allows a system to start immediate fast charging if a USB transceiver is unavailable due to a discharged battery.
