Features - - - - - C-MOS Metal-Gate Process Operating voltage: 1.2V~4.5V Low stand-by current: 1µA at 3V A five lamp flash driver Random or sequence flash - - - - On/Off toggle control 1/10 duty cycle output A built-in oscillator Minimum external ponents General Description The HT2050 is a low cost, low-power CMOS fabricated LSI chip designed for lamp and LED flash drivers. It contains five flash outputs. Each flash output is with a 10m A capability that can implement random or sequential flashing controlled by a single option pin. The chip requires only one external resistor for normal applications. It is very suitable for use in products that require flashing lights, such as gift cards, Christmas decoration, etc. Pin Assignment Block Diagram Pad Coordinates Pad No. 1 2 3 4 5 6 Unit: mil - 21.09 - 9.89 1.31 12.51 23.71 26.23 - 20.9 - 20.9 - 20.9 - 20.9 - 20.9 13.3 Pad No. 7 8 9 10 11 12 26.55 13.35 6.15 - 10.89 - 26.25 -...
