AP4305UKTR-G1

Diodes Incorporated · AC-DC Controllers And Regulators · SOT-26-6

AP4305UKTR-G1 from Diodes Incorporated, in a SOT-26-6. 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 VCTRL input Input pin of the voltage control loop, which uses the 1.21 V voltage reference (VREF 1.186 V to 1.234 V over -40 to +105 °C).
2 GND power_in Ground reference pin for the device.
3 VOUT output Output pin that sinks current only (open-drain style output, low output voltage 200 mV typical at 10 mA sink, 20 V absolute maximum on VCC).
4 ICTRL input Input pin of the current control loop, with the current-sense reference set by VSENSE at 200 mV typical.
5 VSENSE input Input pin of the current control loop that sets the current-limit reference (200 mV typical, 192 mV to 208 mV over temperature).
6 VCC power_in Power supply pin; recommended operating range is 2.5 V to 18 V with an absolute maximum of 20 V.
