# D6211B

**Silicore(芯谷)** · Power Management - Specialized · SOT-23-6

D6211B from Silicore(芯谷), in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ENB/CE | input | Low-active enable input that also serves as the CE pin, where an external capacitor sets the one-shot period (T(one-shot) = 1.3x10^6 x CCE seconds) in one-shot control mode. |
| 2 | GND | power_in | Ground reference pin for the driver. |
| 3 | FBC | input | Forward/backward control input that sets the direction of the H-bridge driver output between OUT1 and OUT2. |
| 4 | OUT1 | output | Driver output 1 of the one-channel bi-directional H-bridge, with a typical current-switch impedance below 3 ohms and a 500 mA maximum output current. |
| 5 | VDD | power_in | Power supply input with a recommended operating range of 2.5 V to 5.5 V (5.0 V typical) and an absolute maximum of 5.5 V. |
| 6 | OUT2 | output | Driver output 2 of the one-channel bi-directional H-bridge, with a typical current-switch impedance below 3 ohms and a 500 mA maximum output current. |
