ME8321AS7G

MICRONE · AC-DC Controllers and Regulators · SOP-7

ME8321AS7G from MICRONE, in a SOP-7. 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 VDD power_in Chip supply pin. Recommended operating range 10V to 30V. UVLO turn-on ~15.5V, UVLO turn-off ~9.5V, OVP ~33V, internal clamp ~35V at 7mA. Requires a bypass capacitor to GND.
2 INV input Output voltage feedback input. Senses the auxiliary winding via an Ra/Rb divider; internal reference 2.0V (±1%). Also drives the cable-drop compensation and 2.4V output-OVP threshold. Absolute-max input range -0.7V to +7V.
3 COMP passive Constant-current loop compensation node; connect an external capacitor to GND. Internal COMP reference ~500mV (490-510mV) used by the CC regulation loop. Absolute-max input range -0.3V to +7V.
4 CS input Primary-side current sense input. Connect a sense resistor Rcs from this pin to GND to program CC output current (Icc = N/2 · 500mV / Rcs). 500ns internal leading-edge blanking; no external RC filter needed. Absolute-max -0.3V to +7V.
5 DRAIN power_out Drain of the integrated 650V high-voltage power MOSFET; connect to the transformer primary winding. BVdss ≥ 650V, Rds(on) ~9Ω typ at Vgs=10V, Id=0.5A. Pins 5 and 6 are internally connected and both must be tied to the primary drain node.
6 DRAIN power_out Drain of the integrated 650V high-voltage power MOSFET; connect to the transformer primary winding. Internally tied to pin 5. BVdss ≥ 650V, Rds(on) ~9Ω typ.
7 GND power_in Device ground reference for all analog and control circuitry as well as the integrated MOSFET source return.
