ME4315AM6G-1

MICRONE · Voltage Reference · SOT-23-6

ME4315AM6G-1 from MICRONE, in a SOT-23-6. 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 VCTRL input Voltage control loop input. Connects to the resistor divider (R1/R2) that senses the output voltage; the internal voltage-loop op-amp compares this against the 1.21V reference to regulate Vout.
2 GND power_in Ground / device return. All internal references and op-amps are referred to this node.
3 VOUT output Controller error-amp output; open-drain / sink-only (VOL ≈ 400mV at 10mA sink). Typically drives the cathode of an optocoupler LED (with pull-up Rcut) to feed back to the primary-side PWM controller. Short-circuit current to VCC is ~27mA (typ), 70mA (max).
4 ICTRL input Current control loop input; inverting node of the current-loop op-amp used to program/compensate the CC threshold. Sources ~21µA from its own pin when driven to -70mV (IIBI).
5 VSENSE input Current-sense input for the CC loop. Compared against the internal 70mV (typ, 68.5-75.5mV) current-limit reference to set the output current limit: I_LIMIT = (V_SENSE · V_REF) / ((V_SENSE + V_REF) · Rss).
6 VCC power_in Supply input, 3V to 36V operating range (36V absolute max). Typical quiescent current 0.85mA. Bypass locally with a ceramic capacitor to GND.
