Am using ULN2003 driver ic to drive the 6 Volts relay. But i think this is not sufficient for any automotive application where their will be a huge noise, spikes , ESD etc., So in order to avoid that i need a proper guidance or circuit with maximum protection and isolation.
The load which am connecting to relay Normally open point is, "DC Geared Motors of 10v to 24 Volts 20Amps", and power source for the motor is Battery with sufficient voltage and current which is connected to the Common point of the relay.
Kindly help me that.
A seems able to drive a 35Amp automotive relay.
You may want to add a snubber diode across the coil.
