BL8023F
300mA Bi-Direction Relay Driver
DESCRIPTION
BL8023F 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.
BL8023F can provide 300mA typical driving
current, which will different according to the
relay coil resistance. The input High Level
Threshold of BL8023F is 2V; it can compatible
with most single chip microcontroller.
BL8023F is available in SOT-23-6 packages.
FEATURES
5 to 36V input voltage range
Low Power Consumption (IQ<1uA)
Input High Level Threshold: 2V, compatible with
most single chip microcontroller
Typical Driving Current: 300mA
Rds(on)=12ohm(Vin=12V, PMOSFET+NMOSFET)
Rds(on)=10ohm(Vin=30V, PMOSFET+NMOSFET)

Level Triggering
If input is driven by voltage level, resistor R1, R2 should be used to insure low voltage standby input. Apply input
voltage according to logic table drives the relay correspondingly (R1, R2=30K-100K, R3, R4=100K, C1, C2=10n,
recommended for removing input spikes; 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).
