uP8206
Battery Protection IC
for 2-Serial to 4-serial-Cell Pack (Secondary Protection)
Features
General Description
The uP8206 series is used for secondary protection of
lithium-ion rechargeable batteries, and incorporates a high-
accuracy voltage detection circuit and a delay circuit. Short-
circuits between cells accommodate series connection of
two to four cells.
