The MC34673AEPR2 from Freescale Semiconductor is a highly integrated battery charger designed for single-cell Lithium-Ion and Li-Polymer batteries. It features a high input voltage capability of up to 28V, eliminating the need for external input over-voltage protection circuits in many applications.
The charger operates with trickle, constant-current (CC), and constant-voltage (CV) charge modes. The CC-mode current is programmable up to 1.2A, with accuracy specified at ±6% over the -40°C to 85°C temperature range. The CV mode is fixed at 4.2V with ±0.7% accuracy over a -20°C to 70°C range. It includes features like charge current thermal foldback and a 2.6V power-on-reset threshold.
Packaged in an 8-UDFN (3x2) surface-mount package, the MC34673AEPR2 is suitable for compact designs. It offers three indication pins for interfacing with microprocessors or LEDs and draws less than 1.0µA leakage current when disabled or without a power supply.
Key specifications include a maximum charge current of 1.2A, a battery pack voltage of 4.2V, and an input over-voltage protection threshold of 6.8V. The operating temperature range is -40°C to 85°C.
