Bi-direction Relay Driver （For magnetic latching relays like BST902 series）

Manual

Pulse input application

2) Voltage input

If input is drived 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;Rs=5-10ohm）
