UCC2807D-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 (swinging between 1/3 VDD and 2/3 VDD) that controls the internal oscillator. |
| 2 | COMP | output | Output of the error amplifier and input of the PWM comparator; it can source and sink current, 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, and the absolute maximum is -0.3V to (VDD + 0.3V). |
| 4 | CS | input | Current sense input to the PWM and overcurrent comparators, with 100ns leading edge blanking after the OUT rising edge and an overcurrent threshold of 1.5V typical. |
| 5 | GND | power_in | Reference ground and power ground for all functions of the part. |
| 6 | OUT | output | Totem-pole output of a high-current gate driver for a power MOSFET, rated for peak currents exceeding 1A (absolute maximum ±1A) and held low when VDD is below the UVLO threshold. |
| 7 | VDD | power_in | Power input; bypass to GND with a ceramic capacitor in parallel with an electrolytic capacitor, with a 13.5V absolute maximum supply voltage (IDD ≤10mA) and a 13.5V typical zener shunt. |
| 8 | DISCH | passive | Provides the low-impedance discharge path for the external RC timing network during normal operation. |
