EG Micro · Gate Drivers · SOP-14

EG21814 from EG Micro, in a SOP-14. 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 HIN input Logic input for the high-side driver, active high: HIN=1 turns the high-side MOSFET on (HO high) and HIN=0 turns it off, with an internal 200K pull-down that keeps the high-side off when the pin is left open.
2 LIN input Logic input for the low-side driver, active high: LIN=1 turns the low-side MOSFET on (LO high) and LIN=0 turns it off, with an internal 200K pull-down that keeps the low-side off when the pin is left open.
3 VSS power_in Ground reference of the chip's logic circuitry.
4 NC unconnected No internal connection; leave floating.
5 COM power_in Power ground for the low-side output driver.
6 LO output Low-side gate drive output that switches the low-side power MOSFET on and off, rated for up to 2.5 A source and 3 A sink peak current (PW≤10 µs) with an absolute maximum of VCC+0.3 V.
7 VCC power_in Chip supply input rated 10 V to 20 V (15 V typical, absolute maximum 20 V), to be decoupled with a high-frequency 0.1 µF bypass capacitor to reduce high-frequency noise.
8 NC unconnected No internal connection; leave floating.
9 NC unconnected No internal connection; leave floating.
10 NC unconnected No internal connection; leave floating.
11 VS power_in High-side floating ground (return for the high-side driver), with an absolute range of VB-20 V to VB+0.3 V.
12 HO output High-side gate drive output that switches the high-side power MOSFET on and off, with an absolute range of VS-0.3 V to VB+0.3 V.
13 VB power_in High-side floating bootstrap supply, rated up to 600 V absolute maximum, fed through an external bootstrap diode and capacitor.
14 NC unconnected No internal connection; leave floating.
