EG12521 from EG Micro, in a SOP-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 | VCC | power_in | Chip supply input, operating range 4V to 20V; a 0.1-1uF high-frequency bypass capacitor is recommended to reduce high-frequency noise at the input. |
| 2 | HIN | input | High-side logic input, active high: 1 turns on the high-side power MOSFET (HO) and 0 turns it off; the datasheet gives V_IH ≥ 2.5V and V_IL ≤ 1.0V. |
| 3 | LIN | input | Low-side logic input, active high: 1 turns on the low-side power MOSFET (LO) and 0 turns it off; the datasheet gives V_IH ≥ 2.5V and V_IL ≤ 1.0V. |
| 4 | GND | power_in | Chip ground terminal. |
| 5 | LO | output | Low-side gate drive output that controls the on/off state of the low-side power MOSFET. |
| 6 | VS | power_in | High-side floating ground (high-side return), the reference node for the HO driver. |
| 7 | HO | output | High-side gate drive output that controls the on/off state of the high-side power MOSFET; output sources up to 0.8A and sinks up to 1.2A (pulse width ≤10µs). |
| 8 | VB | power_in | High-side floating supply, charged through the external bootstrap diode and capacitor; the datasheet rates VB from -0.3V to 600V absolute maximum. |
