T0816M

The T0816M is one of the T0816 series.The T0816M is a laser diode driver for the operation of a grounded laser diode for CD-RW drives.T0816M includes three channels for three different optical power levels which are controlled by a separate IC.The read channel generates a continuous output level whereas channels 2 and 3 are provided as write channels with very fast switching speeds.Write current pulses are enabled when a 'low'signal is applied to the NE pins.All channel are summed together at the IOUT pin.Each channel can contribute up to 250mA to the total output current of up to 300 mA.A total gain of 100 (read channel),250 (channel 2)and 150 (channel 3) are 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 T0816M are:(1)current-controlled ouput current source,3 input channels; (2)low-power consumption; (3)output current per channel to 250 mA; (4)total ouput current to 300 mA; (5)rise time 1.0ns ,fall time 1.1 ns; (6)on-chip rf oscillator; (7)control of frequency and swing by use of 2 external resistors; (8)osicillator frequency range from 200 MHz to 500 MHz; (9)osicillator swing to 100mA; (10)single 5V power supply ; (11)common enable,disable input ; (12)TTL/CMOS control signal; (13)small SSO16 package and QFN16 package.

The absolute maximum ratings of the T0816M can be summarized as:(1)supply voltage:-0.5~6.0V; (2)input voltage at IR,12,13:-0.5~2.0V; (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 T0816M such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
