**Texas Instruments** · LED Drivers · SOIC-8

TPS92020DR 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 | DT | input | Sets the dead time of the high-side and low-side switch driving signals via a resistor to ground, referenced to the internal 2.25-V reference, and dead time is clamped to a minimum of 120 ns so any setting below 120 ns defaults to 120 ns. |
| 2 | RT | input | Current flowing out of this pin sets the switching frequency, where a resistor to ground sets the minimum frequency, a resistor in series with the opto-coupler transistor limits the maximum frequency, and the absolute maximum RT current range is -5 mA. |
| 3 | OC | input | Overcurrent protection pin: gate drivers are actively pulled low above 1 V, recover with soft start after falling below 0.6 V, and the device latches off when the voltage exceeds 2 V until VCC drops below UVLO. |
| 4 | SS | input | Sets the soft-start time with a capacitor to ground, and pulling this pin below 1 V disables the device for ON/OFF control. |
| 5 | GD2 | output | Low-side/high-side gate driver output connected to the gate driver transformer primary to drive the half bridge, rated for continuous gate drive current of ±25 mA as an absolute maximum. |
| 6 | GND | power_in | Ground reference for the device; all voltages on the device are specified with respect to GND. |
| 7 | VCC | power_in | Bias supply input that must be connected to a supply below 20 V, with the device enabled above 10.5 V, in UVLO below 9.5 V, and in VCC overvoltage protection above 20 V (absolute maximum VCC 22 V). |
| 8 | GD1 | output | High-side/low-side gate driver output connected to the gate driver transformer primary to drive the half bridge, rated for continuous gate drive current of ±25 mA as an absolute maximum. |
