EG21867 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 operating supply input, specified at 10V to 20V in the pin table, with a 0.1uF high-frequency bypass capacitor recommended to reduce high-frequency noise at this pin; absolute maximum VCC is 20V. |
| 2 | HIN | input | Logic input, active high, that controls turn-on and turn-off of the high-side power MOSFET (1 = on, 0 = off), with a logic-high threshold of 2.8V minimum and a logic-low threshold of 1.3V maximum. |
| 3 | LIN | input | Logic input, active high, that controls turn-on and turn-off of the low-side power MOSFET (1 = on, 0 = off), with a logic-high threshold of 2.8V minimum and a logic-low threshold of 1.3V maximum. |
| 4 | GND | power_in | Ground reference pin of the chip. |
| 5 | LO | output | Gate drive output that switches the low-side power MOSFET on and off, with a source/sink capability of 4A (peak, PW ≤ 10uS) per the electrical characteristics. |
| 6 | VS | power_in | High-side floating ground, the reference for the high-side driver, which must stay within VB-20V to VB+0.3V per the absolute maximum ratings. |
| 7 | HO | output | Gate drive output that switches the high-side power MOSFET on and off, with a source/sink capability of 4A (peak, PW ≤ 10uS) per the electrical characteristics and an absolute maximum of VB+0.3V. |
| 8 | VB | power_in | High-side floating supply for the high-side driver, with an absolute maximum rating of 600V (VB to GND, per the absolute maximum table) and a bootstrap capacitor connected between VB and VS. |
