10.4 Enable signals

LTBRZ3-C Series can be turned ON or OFF by applying proper signals to the input pins named PNP
enable and NPN enable.
Signal
PNP enable
NPN enable
Leave signals unconnected if not used
Do not try to force both PNP and NPN simultaneously.
The table below lists typical current consumption for both lines (PNP, NPN) and is valid for a single
module.
Driving the enable with a 3.3 V signal is not recommended.
