# VPS8505

**VPSC** · Power Management - Specialized · SOT-23-6

VPS8505 from VPSC, in a SOT-23-6. 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 | VD1 | output | Complementary transformer driver output 1; LDMOS channel output with drain voltage rating to 24V and 1.7A current clamp limit. |
| 2 | VCC | power_in | Power supply input, 2.3-6V input voltage range; bypass to GND with 1µF capacitor placed close to device. |
| 3 | VD2 | output | Complementary transformer driver output 2; LDMOS channel output with drain voltage rating to 24V and 1.7A current clamp limit. |
| 4 | GND | power_in | Logic circuit and analog circuit ground reference. |
| 5 | EN | input | Active-high enable control pin for chip operation; chip disabled below 0.8V, enabled above 1.8V with internal 475kΩ pull-down resistor to GND. |
| 6 | CLK | input | External frequency synchronization input (100-1600 kHz); operates at internal frequency 363-485 kHz when held to GND to avoid external interference. |
