General Description
The HT201XX series is a low cost, low power
CMOS LSI chip designed for lamp and LED
flash drivers. It can be operated without any
external components, thus suitable for applica-
tions on flashing badges, gift cards, flashing
earrings, and other products that require flash-
ing lights.
