Description
The M62240FP is a general purpose battery charger control IC. It can control all of the sequence needed for battery charging, it also has functions such as detection of battery temperature, a protection against over-current/voltage, a safety timer and so on. Moreover, it can adapt to charge Ni-Cd, Ni-MH batteries by adding few peripheral components. The IC has the feedback control of the charge current and output voltage.
   
Features
• Low voltage (3 V) operation
• Built-in following functions and circuits;
    - CR oscillator for internal logic
    - Initialization timer and safety timer for ∆V error detection
        and over-charging
    - D/A converter and shift registers to maintain the peak voltage
        of battery
    - Main output SW driving circuits
    - LED driving circuit for displaying the status of the charging
    - System reset circuit for detecting the power supply voltage
    - Temperature detection circuit for the Ni-MH battery
    - Voltage and current control circuits for feedback
        to the primary side of the SMPS.
    - Protective functions including detection of over-voltage
        in charge mode and over-current in adapter mode and so on
   
Application
    Battery charger for video cameras and handheld telephones, etc.
