BL8023DCB6TR

BL Shanghai Belling · Relay / Coil Drivers · SOT-23-6

BL8023DCB6TR from BL Shanghai Belling, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OB output Output B. Bi-directional relay coil driver output B. Connects to one terminal of the magnetic latching relay coil; high-impedance when both inputs are equal, driven high/low per the logic table for forward/reverse coil energization.
2 GND power_in Ground reference for the device. Connect to system ground / return of the input supply (VIN).
3 A input Input A. Logic control input; high-level threshold Vth=3V (typ. at Vin=12V), equivalent input resistance ~500 kOhm. Recommended drive pulse width 100 ms. Combined with Input B per the logic table to select forward drive / backward drive / hold.
4 OA output Output A. Bi-directional relay coil driver output A. Connects to the opposite terminal of the magnetic latching relay coil from OB; high-impedance when both inputs are equal, driven high/low per the logic table for forward/reverse coil energization.
5 VIN power_in Supply input voltage. Operating range 5 V to 36 V (40 V absolute max). Quiescent current typically <1 uA. A current-limiting resistor Rs may be inserted in series when Vin > 20V.
6 B input Input B. Logic control input; high-level threshold Vth=3V (typ. at Vin=12V), equivalent input resistance ~500 kOhm. Recommended drive pulse width 100 ms. Combined with Input A per the logic table to select forward drive / backward drive / hold.
