GR8837TCG 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 pin. |
| 2 | COMP | input | Voltage feedback pin rated -0.3V to 7V absolute maximum for duty cycle control via photo-coupler, with green-mode start voltage of 1.5V and burst mode start voltage of 0.85V. |
| 3 | RTL | input | Resistor trigger pin rated -0.3V to 7V absolute maximum for auto recovery mode, triggering OVP protection when voltage exceeds 3.5V and OTP protection when voltage falls below 1V. |
| 4 | CS | input | Current sense input pin rated -0.3V to 7V absolute maximum with maximum input voltage of 0.85V in auto recovery mode, 350ns leading-edge blanking time, and 1MΩ input impedance. |
| 5 | VCC | power_in | Power supply input pin rated 0V to 30V absolute maximum with UVLO turn-on threshold of 11.3V and UVLO turn-off threshold of 6.8V. |
| 6 | OUT | output | Gate driver output pin rated -0.3V to VCC + 0.3V absolute maximum for external MOSFET with 300mA driving capability, internally clamped to 13V, output low level less than 1V and output high level greater than 8V at 15V supply with 20mA load. |
