Description
The M62258FP is designed as general purpose battery charger control. The M62258FP has function which require for
the battery charge control on single chip. Not only the combination of M62258 and microcomputer capable of handing
battery charge control, but also it is capable of monitoring battery temperature, prevent from over current or voltage,
using minimal peripherals. It also has feedback function to the primary side of SW power supply, which can used to
control feedback of charge current and output voltage.
Features
• Built-in 3 wire serial data interface function for MCU.
• Built-in multiplexer and level magnification circuit with 2 input ports.
• Built-in low input/output operation 5 V voltage regulator function. (Pre drive type)
• Built-in charge current/output voltage control circuit.
Application
Video camera, mobile phone and general battery charger for other digital equipment
