# MAX627ESA+

**Maxim Integrated** · Pre-ordered Chips · SOIC-8

MAX627ESA+ from Maxim Integrated, in a SOIC-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 | N.C. | unconnected | No connection internally. |
| 2 | INA | input | Channel A TTL/CMOS-compatible input (logic 1 min 2.4V, logic 0 max 0.8V), non-inverting to OUTA. |
| 3 | GND | power_in | Ground, the supply return for VDD (VDD rated +20V to GND max). |
| 4 | INB | input | Channel B TTL/CMOS-compatible input (logic 1 min 2.4V, logic 0 max 0.8V), non-inverting to OUTB. |
| 5 | OUTB | output | Channel B non-inverting power MOSFET gate driver output with 2A peak current at VDD = 18V. |
| 6 | VDD | power_in | Positive supply input, 4.5V to 18V operating range (absolute maximum +20V to GND). |
| 7 | OUTA | output | Channel A non-inverting power MOSFET gate driver output with 2A peak current at VDD = 18V. |
| 8 | N.C. | unconnected | No connection internally. |

## CAD (KiCad official)

- Symbol: `MAX627ESA+`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `max627esa-etched.step` / `max627esa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `max627esa.step` / `max627esa.glb` are the bare package body.
