| Samsung Electronics Develops Chips for Recharging Devices
|
|
August 27, 1998 (SEOUL) -- Samsung Electronics Co., Ltd. said it developed
two microcontroller units for use in mobile phone battery-recharging
devices.

The new non-memory semiconductors will control the functions of a lithium-ion
battery recharger and detect the charged state of batteries. Production
of the chips will begin in September, Samsung Electronics said.
The company expects sales of the two microchips in Korea will lead to
an annual import substitution effect worth over 25 billion won (US$19
million).
The two types are those of 10 bits with five channels and 8 bits with
eight channels.
Each channel receives signals on the batteries to be recharged, including
voltage, current and temperature. The analog signals are then converted
into digital signals via the microchips to indicate the recharging state
with numbers on a display panel.
Samsung Electronics said it will develop a similar chip with 11 channels
capable of recharging two batteries at the same time, by the end of
this year.
