It seems like there are more low side driver ic s available but what s actually the pros and cons from the ecu designer point of view.
High side relay driver ic.
High side driven low side driven bi stabil.
There are various types of relay driver ics such as a high side toggle switch low side toggle switch bipolar npn transistor darlington transistor n channel mosfet uln2003 driver ic.
This requires both a robust low on resistance power switch and accurate analog circuitry for diagnostic protection and control functions.
