T0800TS45E

The T0800TS45E is one of the T0800 series.The T0800TS45E is a laser diode driver for the operation of two different, grounded laser diode for DVD-RAM(650nm)and CD-RW(780 nm).It includes five channels for five different optical power levels which are controlled by a separate IC.The read channel generates a continuous output level .The channels2 to 5 are provided as write channels with very fast switching speeds. when a 'low'signal is applied to the NE pins.All channels are summed together and switched to one of the two outputs IOUTA or IOUTB by the select input SELA.Each channel of T0800TS45E can contribute up to 200mA to the total output current of up to 250mA.A total gain of 100 is provided between each reference current input and the output.Although the reference inputs are current inputs voltage control is possible by using external resistors.

Features of the T0800TS45E are:(1)current-controlled ouput current source with 5 input channels; (2)2 selectable outputs for grounded laser diodes; (3)output current per channel up to 200mA; (4)total ouput current to 250mA; (5)rise time 1.1 ns; (6)on-chip rf oscillator; (7)control of 2 different frequencies and swings by use of 4 external resistors; (8)oscillator frequency range from 200MHz to 600 MHz; (9)oscillator swing to 100 mA; (10)single 5V power supply ; (11)common enable/disable input ; (12)TTL/CMOS control signals; (13)small SSO24 package and QFN28 package.

The absolute maximum ratings of the T0800TS45E can be summarized as:(1)supply voltage:-0.5~6.0V; (2)input voltage at IR,12,13:-0.5~0.5V; (3)input voltage at NER,NE2 NE3,ENOSC:-0.5~VCC+0.5V; (4)output voltage:-0.5~VCC-1 V; (5)power dissipation:0.7~1W; (6)junction temperature:150; (7)storage temperature range:-65~125.If you want to know more information about T0800TS45E such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
