AT8222 from ZHONGKEWEI, in a ESOP-8. 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 | GND | power_in | Chip ground; the GND pin and the exposed thermal pad must both be connected to power ground. |
| 2 | IN2 | input | Logic input that controls the H-bridge output state together with IN1 per the truth table, with logic-high VIH of 2 V to 5.25 V. |
| 3 | IN1 | input | Logic input that controls the H-bridge output state, with a built-in pull-down resistor (typically 100 kΩ), logic-high VIH of 2 V to 5.25 V, and PWM input frequency up to 100 kHz. |
| 4 | VREF | power_in | Reference voltage input that sets the H-bridge peak drive current; recommended range 0.5 V to 4 V. |
| 5 | VM | power_in | Chip and motor supply, recommended 5.5 V to 24 V (absolute maximum -0.3 V to 28 V), which requires supply filtering with at least 47 µF electrolytic capacitance placed close to the device. |
| 6 | OUT1 | output | H-bridge output 1; positive current is defined as flowing from OUT1 to OUT2, with peak output current of ±2.8 A. |
| 7 | ISEN | input | H-bridge current-sense input that connects to a sense resistor to ground, or directly to ground if current limiting is not needed, with a sense voltage limit of -0.3 V to 0.5 V. |
| 8 | OUT2 | output | H-bridge output 2, paired with OUT1; recommended continuous output current 1.5 A and peak output current 2.2 A. |
| 9 | PPAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
