driving a 12 V realy coil

hey guys i want some help
i want to driving 12V 60 ohm realy coil using 12V 400 mA battery now i have to control the power supply of the battery to relay using microcontroller so can u give me a circuit with the specification of all necessary transistor , resistors and other components needed..

You may use this relay driver if your microcontroller gives out a "HI" logic when triggered. If not you may convert the same or use a PNP transistor in place of NPN.... Cheers
