RECOMMENDED OPERATING CONDITIONS
VM
VCLAMP
IOUT
Power supply voltage range
Output clamp voltage range(1)
Continuous output current, single channel on, TA = 25°C, SOIC package(2)
Continuous output current, four channels on, TA = 25°C, SOIC package(2)
Continuous output current, single channel on, TA = 25°C, HTSSOP package(2)
Continuous output current, four channels on, TA = 25°C, HTSSOP package(2)
(1) VCLAMP is used only to supply the clamp diodes. It is not a power supply input.
(2) Power dissipation and thermal limits must be observed.
