Product Number: LTC7000A
Hello,
I am using the LTC7000A as a high-side switch for 4 high-current relays. These relays use a coil economizer, which requires 3.8 Amps of current for 0.13 seconds, and then a hold current of 0.12 Amps once the relay is closed.
in addition to this, there is about 220 uF of bulk capacitance that needs to be charged up gradually.
Last of all, the relay coils are external to my PCB on wires about 300 cm in length, and the relays are inductive. There is a concern about negative voltage spikes.
Does this design reasonably accommodate for these concerns? Any feedback is appreciated. Thank you!
