For single coil latching relays the MAX14874 IC can be used directly. It is essentially a H-bridge with driver circuitry built in, as well as freewheeling diodes so there are very few external components necessary.
For dual coil latching relays the MAX14874 could be used also. Taking the G6EK-134P as an example, if terminal 3 were to be pulled high then terminals 1 and 6 could be connected to the MAX14874 M1 and M2 pins respectively to drive each of the latching coils.
