The Freescale Semiconductor MC34675AEPR2 is a high-input-voltage Li-Ion battery charger designed for single-cell applications. It supports an input voltage up to 28V, eliminating the need for external input over-voltage protection circuits in many handheld devices.
This charger integrates a 4.85V/10mA linear regulator capable of powering sub-systems like USB transceivers. The charge cycle includes trickle, constant-current (CC), and constant-voltage (CV) modes. The CC mode current is programmable up to 1A, with voltage accuracy of ±0.7% and current accuracy of ±6% over the -40°C to 85°C temperature range. The constant voltage is fixed at 4.2V.
A charge current thermal foldback feature limits the charge current if the internal IC temperature reaches 120°C. The device also includes input over-voltage protection. It is available in an 8-UDFN package and is surface-mount compatible.
This charger is suitable for portable media players, Bluetooth accessories, and cell phones, offering a compact and efficient charging solution.
