It depends on the relays too. I've been driving 8 small relays directly with I2C I/O expander PCA9555.seyyah said:Are there any ICs for driving relays? (Especially multiple relays)
I need to drive 32 NEC EA2 relays on my pcb but I want to use minimum number of driver ICs.
I was thinking about driving 4 relays from 1 output of ULN 2803 but from the datasheet I couldnt find out whether its possible or not..Besides I dont have any samples so I cant make any experiments.
Do you have suggestions for such a driver IC? Only requirement is to operate between -40 C to 85 C.
I need a response as soon as possible.
