I found a driver chip, MAX5054 but it seems obsolete now and can't find a source of it.
I need to use a latching relay to save 30mA of current, from powering (3) relays. I just need to flip the states of these relays and it's a waste of 30mA to keep these relays energized.
Anyone know of a MAX5054 replacement? or some other single-coil latching relay driver that accepts a single control input?
My microprocessor isn't controlling the relays directly.
Instead, another chip is the one that sends the logic high/low which in turn control the relays on/off via a transistor driver. In effect, I only have one data line for each relay.
The microprocessor just talks to this other chip via SPI to send commands.
