1. Description

The T0816 is a laser diode driver for the operation of a grounded laser diode for

CD-RW drives. It 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 channels are summed together at the IOUT pin. Each channel can contribute up to

250 mA 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.

An on-chip RF oscillator is provided to reduce laser mode hopping noise during read

mode. Frequency and swing can be set by two external resistors. Oscillation is

enabled by a ‘high’ at the ENOSC pin. Complete output current and oscillator switch-

off is achieved by a ‘low’ at the ENABLE input.
