BL8123 is a bi-direction relay driver circuit, used to control the magnetic latching relay, with large output capability, ultra-low power consumption. It can be widely used in smart meters and other pulses, level control applications. BL8123 can provide 400mA typical driving current, which will different according to the relay coil resistance. The input High Level Threshold of BL8123 is 1.5V, making it compatible with most single chip microcontroller. BL8123 is available in SOT23-6 package.
