www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC34671 Rev. 1.0, 01/2008 High Input Voltage 600mA Charger for Single-cell Li-Ion Batteries 34671 The MC34671 is a cost-effective fully-integrated battery charger for POWER MANAGEMENT IC Li-Ion or Li-Polymer batteries. The high input voltage, up to 28V, eliminates the input over-voltage-protection circuit required in handheld devices such as cell phones, Bluetooth accessories and MP3 players. A typical charge cycle includes trickle, constant-current (CC) and constant-voltage (CV) charge modes. The CC-mode current is programmable up to 600mA with an external resistor. The voltage across the external resistor is also used to monitor the actual charge EP SUFFIX (PB-FREE) 98ASA10774D current.
