UCC27517ADB

Tokmas · Gate Drivers · TSOT-23-5

UCC27517ADB from Tokmas, in a TSOT-23-5. 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 VDD power_in Power supply of the gate driver, operating from 4.5 V to 24 V and decoupled by ceramic capacitors, with 0.1 uF plus 1 uF or 10 uF recommended.
2 GND power_in Power ground that must be soldered directly to the ground planes for improved thermal performance and electrical contact.
3 IN+ input Non-inverting TTL-compatible logic input that floats low; it carries the PWM signal in non-inverting operation and is connected to VDD in inverting operation.
4 IN- input Inverting TTL-compatible logic input that floats low; it is connected to GND in non-inverting operation and carries the PWM signal in inverting operation.
5 OUT output Gate driver output rated for 4 A peak source and 4 A peak sink current.
