ME8202SG

MICRONE · AC-DC Controllers and Regulators · SOP-8

ME8202SG from MICRONE, in a SOP-8. 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 GND power_in Device ground reference. All internal voltages and the current-sense return are referenced to this pin.
2 FB input Feedback input pin. PWM duty cycle is determined by the voltage at this pin combined with the current-sense signal at pin 6 (SENSE). Open-loop voltage ≈5.8V, burst-mode threshold ≈1.7V, power-limit threshold ≈4.4V, input impedance ≈7.2kΩ.
3 VIN input High-voltage startup and line-voltage-sense input. Connected through a large-value startup resistor (typ. 2MΩ) to the rectified AC line for IC startup supply and for OCP line-voltage compensation. Absolute max 30V DC.
4 RI passive Internal oscillator frequency setting pin. A resistor from RI to GND programs the PWM switching frequency per Fosc = 1560 / RI(kΩ) [KHz]. Recommended RI range 24-31kΩ (operating range 12-60kΩ). Open-load voltage ≈2V.
5 RT input Over-temperature protection sensing input. An NTC resistor (in series with a regular resistor) is connected from RT to GND; the pin sources ≈70µA and OTP trips when V(RT) falls below VTH_OTP ≈1.065V. Open voltage ≈3.5V.
6 SENSE input Current-sense input. Connected to the top of the MOSFET source current-sense resistor for cycle-by-cycle OCP. Has 250ns leading-edge blanking and ~30kΩ input impedance; OCP threshold ≈0.9V at IVIN=0 (line-compensated down to ~0.81V at IVIN=150µA).
7 VDD power_in Chip DC supply pin, typically fed from an auxiliary transformer winding. Recommended operating range 12-23V; UVLO enter ≈10.5V, UVLO exit (start) ≈16.5V, internal Zener clamp ≈35V, OVP shutdown ≈25V.
8 GATE output Totem-pole gate-drive output for the external power MOSFET. Internally clamped to ≈16V for MOSFET gate protection. VOH ≥11V at IO=20mA, VOL ≤0.3V at IO=-20mA, tr ≈120ns / tf ≈50ns into 1nF.
