Diodes Incorporated · AC-DC Controllers & Regulators · SO-8

APR3415BMTR-G1 from Diodes Incorporated, in a SO-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 DRISR output Synchronous rectification MOSFET drive output; drive output voltage is at least 3.7V at VCC=5V and the pin is rated -0.3 to 6V.
2 VDET bidirectional Synchronous rectification sense input and dynamic function output, connected to DRAIN through a resistor; rated -2 to 50V.
3 AREF passive Programs a voltage reference with a resistor from AREF to GND to enable the synchronous rectification MOSFET drive signal; rated -0.3 to 6V.
4 VCC power_in Power supply connected with system output; recommended 3.3 to 6V, absolute maximum -0.3 to 7.5V.
5 GND power_in Source pin of internal MOSFET, connected to Ground (pins 5 and 6 are both GND).
6 GND power_in Source pin of internal MOSFET, connected to Ground (pins 5 and 6 are both GND).
7 DRAIN passive Drain pin of internal MOSFET (pins 7 and 8 are both DRAIN); rated -2 to 50V.
8 DRAIN passive Drain pin of internal MOSFET (pins 7 and 8 are both DRAIN); rated -2 to 50V.
