4.2.2. Power control digital input connections
If•the•active•high•digital•input•is•configured•to•wake•up•the•module:
• • The•power•control•digital•input•is•usually•connected•to•the•vehicle•ignition,•but•it•can•be•connected•
to•any•power•source•in•a•system.
• • To•protect•the•harness•that•connects•the•CM0504•to•the•ignition,•place•a•fuse•of•200•mA•or•higher•in•
the•circuit•that•feeds•the•CM0504.
• • When•battery•power•(VBATT)•is•connected,•and•the•power•control•digital•input•is•inactive,•the•
CM0504•will•go•into•sleep•mode.
• • The•CM0504•has•‘Wake•on•CAN’•capability.•Even•when•it•is•not•configured•for•wake•on•CAN,•the•bus•
must•be•completely•silent•in•order•for•the•CM0504•to•stay•in•low•power•sleep•mode.•Until•the•correct•
wakeup•conditions•are•sensed,•the•CM0504•will•appear•“off”•(outputs•off•and•no•CAN•tx)•but•there•is•
no•way•to•keep•its•power•supply•off•if•there•is•CAN•activity•on•the•bus.•
If•your•CM0504•must•always•be•powered,•the•power•control•digital•input•does•not•need•to•be•used.•The•
CM0504•can•be•configured•to•always•be•powered•using•the•CM0504•Configuration•Tool•software.
