# Can we use 555 timer in automotive electronic circuit? [closed]

Can we use 555 timer IC in autmotive electronics design? If not then please suggest an IC in order to create dealy at laod side.

• Why not? Pick one for automotive application and use it – Gregory Kornblum Jun 4 '18 at 6:07
• @jsotola : it is 2 leds in sereis with V( typ)=2.8V, and would like to provide 10 microsec delay between them. – NSR Jun 4 '18 at 6:33
• Not without protection. 'Automotive' means survive sustained -12v or +24v, and transient +160v, for bad jumpstarting and alternator load dump respectively. Otherwise, go for it. – Neil_UK Jun 4 '18 at 6:37
• @Neil_UK does it really mean that? Usually, automotive parts means AEC-Q100, which puts some heavy constraints on temperature operating range, electrostatic discharge and stuff like that, but I doubt automotive ICs can really withstand +160V transients, or even 24V, can they? – dim lost faith in SE Jun 4 '18 at 7:42

In principle you CAN use anything, as long as it fits within the specifications for your automobile device/part.

Note for the NE555 there is a similar SE555 See example from TI, which is suitable for military purposes (with disclamer), which has increased specifications.
