MC34673AEPR2 Description

Short technical summary and product information.

The MC34673AEPR2 from NXP Semiconductors is a highly integrated and cost-effective battery charger IC specifically designed for single-cell Lithium-Ion or Li-Polymer batteries. It supports a programmable charge current up to 1.2A and features a constant voltage charge mode with a fixed 4.2V output and 0.7% accuracy over a -20°C to 70°C temperature range.

 

This charger IC includes essential protection features such as over-voltage protection (OVP) with a 6.6V threshold and charge current thermal foldback to limit current when the internal IC temperature rises. It operates with a minimum input voltage of 2.6V and a maximum input voltage of 28V, eliminating the need for external input over-voltage protection circuits in many handheld devices.

 

The MC34673AEPR2 is available in an 8-UDFN (3x2) surface mount package. It offers three indication pins (PPR, CHG, and FAST) for interfacing with microprocessors or LEDs. When disabled or without a power supply, it draws less than 1.0µA leakage current from the battery, making it suitable for power-sensitive applications like PDAs, cell phones, portable video game players, and digital still cameras.
