The HT–2050 is a low cost, low-power C-MOS LSI designed for lamp and
LED flash driver. It has five flash outputs with 10mA drive capability that can
implement random or sequence flashing function controlled by one option pin.
It only requires one external resistor for typical application. It is very suitable
for the use of the flash products such as disco glasses, disco hat, gift card,
X’mas decoration and so forth.
