EG Micro · Motor Driver ICs · SOP-8

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.
