KY8023 400mA Bi-Direction Relay Driver GENERAL DESCRIPTION FEATURES KY8023 is a bi-direction relay driver circuit, used to ⚫ Input voltage : 5V~40V control the magnetic latching relay, with large output ⚫ Recommended supply voltage with relay load capability, ultra-low power consumption. It can be : 5V~30V widely used in smart meters and other pulses, level ⚫ ISS＜1μA (high impedance state) control applications. ⚫ Input high level threshold : 1.3V ⚫ Typical driving current : 400mA ⚫ Rdson=7Ω (VIN=12V, PMOSFET+NMOSFET) KY8023 can provide 400mA typical driving current, which will different according to the relay coil resistance. Maximum : 800mA (VIN≤15V) The maximum driving current can reach 800mA when Rdson=5Ω (VIN=30V, PMOSFET+NMOSFET) the supply voltage is equal to or below 15V. The input ⚫ Fly-wheel diode forward voltage : 1.3V(IS=1A) high level threshold VTH is 1.3V. ⚫ Environment temperature : -40 ~ +85℃ ⚫ SOT23-6L and SOP-8 packages KY8023 is available in SOT23-6L and SOP-8 packages.

Relay will operate as logic table stated (VIN should be less than the power supply voltage, Rs is current-limiting resistor, it can be ignored in the voltage is below 20V, i.e. Rs=0). The recommended pulse width=100ms. The length of the intervals should be longer than 100ms. These intervals include: intervals between forward drive pulse and next backward drive pulse, intervals between forward drive pulse and next forward drive pulse, intervals between backward drive pulse and next forward drive pulse, intervals between backward drive pulse and next backward drive pulse.
