GENERAL PURPOSE BATTERY CHARGER CONTROL IC
PIN CONFIGURATION (TOP VIEW)
DESCRIPTION
The M62258FP is designed as general purpose battery charger
control. The M62258FP has function which require for the
batterycharge 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 2input ports.
•Built-in low input/output operation 5V voltage regulator function.
(Pre drive type)
•Built-in charge current/output voltage control circuit.

Symbol
The serial data input pin which used to receive 8 bit wide serial data
The shift clock input pin which tales the input signal of DI pin to 8 bit shift register by the
rising edge of clock signal
When this pin is "Low", DI pin can receive the data into the 8 bit shift register. The each
bit will be latched at rising edge of the clock signal
The output pin of the amplified A-D data
The reference voltage output pin of the A-D converter
The A-D converter input pin
The current sense input pin
The main switch driver output pin (Open collector)
The stabilized +5V output pin
The pre-drive pin which used to connect the external PNP Tr
