MEL7136BM5G-8001

MICRONE · LED Drivers · SOT-23-5

MEL7136BM5G-8001 from MICRONE, in a SOT-23-5. 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 NC unconnected No connection; this pin is listed as NC in the MEL7136B SOT23-5 pin assignment.
2 GND power_in Ground reference pin for the MEL7136B controller.
3 VDD power_in Power input; the supply range is 2.7V to 18V, and the absolute maximum input voltage is 18V.
4 CS input Output current detection input; the CS voltage is 95 mV min, 100 mV typical and 105 mV max, and the voltage on LED and CS is limited to -0.3 V to VDD+0.3 V.
5 EXT output Drives the external NMOS gate; the maximal EXT voltage is 2.5 V min, 3.6 V typical and 4.5 V max at VDD=5.0 V and VCS=0 V, and the absolute maximum voltage on EXT is 6 V.
