High-Voltage Drivers
Table B-5 lists the high-voltage driver characteristics when sinking drivers
or sourcing drivers are used.
Sinking Driver
The sinking-driver IC can handle a maximum of 1.38 A (500 mA for any
channel), or 75 mA per channel on average if all channels are ON, at 60°C.
The absolute maximum power that the driver IC can dissipate depends on
several factors. The sinking ICs saturation voltage is 1.6 V DC max per
channel.
The sinking drivers source voltage must range from 2 V to 48 V DC.
