UCC2807DTR-1 from Texas Instruments, 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 | TRIG | input | Oscillator timing input with an RC-type charge/discharge signal controlling the internal oscillator; oscillator signal minimum is 1/3 VDD and maximum is 2/3 VDD. |
| 2 | COMP | output | Output of the error amplifier and input of the PWM comparator; it can source and sink current, is internally current limited, and forcing it to GND gives zero duty cycle. |
| 3 | FB | input | Inverting input to the error amplifier; keep connections short and stray capacitance small for best stability. |
| 4 | CS | input | Current sense input to the PWM and overcurrent comparators, with a 100ns leading edge blanking after the OUT rising edge and a 1.5V typical overcurrent threshold. |
| 5 | GND | power_in | Reference ground and power ground for all functions of the part. |
| 6 | OUT | output | High current totem pole gate driver output with peak currents exceeding 1A (absolute maximum ±1A), actively held low when VDD is below the UVLO threshold. |
| 7 | VDD | power_in | Power input connection; absolute maximum 13.5V supply (IDD ≤10mA), to be bypassed to GND with a ceramic capacitor in parallel with an electrolytic capacitor. |
| 8 | DISCH | output | Oscillator discharge pin providing the low impedance discharge path for the external RC network during normal operation. |
