GR1231RCG from Grenergy, in a SOT-26. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin. |
| 2 | COMP | input | Voltage feedback pin for photo-coupler duty cycle control or input voltage detect pin via resistor for brown-in protection, absolute maximum -0.3 to 6.0V. |
| 3 | QRD | input | Quasi-resonant detection pin with integrated OVP (3.5V threshold) and brownout protection, voltage clamped to -0.3 to 4.6V. |
| 4 | CS | input | Current sense input pin for MOSFET current detection, maximum input voltage 0.85V at low line (on-time >6μs) or 0.52V at high line (on-time <5μs), 1MΩ input impedance. |
| 5 | VCC | power_in | Power supply input pin with operating range 9.5-26.5V, absolute maximum 30V, OVP threshold 28V, requires 2.2-10μF capacitor. |
| 6 | OUT | output | Gate driver output for external MOSFET, output levels 1V (low) / 8V (high) at 15V VCC with 1.5kΩ load, 13.5V gate clamp, 330ns rise time / 45ns fall time at 1000pF load. |
