Overview
BL8023 is a bi-directional relay drive integrated circuit, used to control the work of magnetic holding relay, with output Current, static power consumption characteristics of small, can be widely used in smart meter production and other uses of the class Relay industry.

main indicators
1) operating voltage at 5-16V, static power consumption <10nA
2) input level conversion level of about 2V, compatible with a variety of single-chip
3) Typical drive current 300mA, and according to the relay itself, the internal resistance of the coil is different (drive current equal to The supply voltage is divided by the chip itself driving the internal resistance and the relay coil internal resistance of the chip itself is driven Resistance: 15Ω for supply voltage 8V for 10V for power supply voltage and 10Ω for supply voltage 14V).
4) Maximum drive current of 800mA (refers to the chip can withstand the relay coil inductance recoil current value. This value is related to the supply voltage, 800mA is the value of the general operating voltage of 12V. In the pole Limit operating voltage 16V, the drive current should be less than 300mA).
5) Operating temperature range: -40°C - 80°C
6) can drive all products of the Tete magnetic protection relay 902 series, especially at the supply voltage 7.5-15V can drive 100A products.
7) can drive Wenzhou Wanjia WJ301-306 products, especially in the power supply voltage 9.5-14.5V, Drive the internal resistance of about 16 ohms WJ306 three-phase relays.
