MEL7136BM5G

MICRONE · LED Drivers · SOT-23-5

MEL7136BM5G 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; the datasheet lists this pin as NC for the MEL7136B in SOT23-5.
2	GND	power_in	Ground reference for the driver.
3	VDD	power_in	Power input, specified from 2.7 V to 18 V, with absolute maximum VDD of 18 V.
4	CS	input	Output current detection input; the CS reference voltage is 95 mV min, 100 mV typ, 105 mV max, and voltage on CS is limited to -0.3 V to VDD+0.3 V.
5	EXT	output	Drives the external NMOS gate; absolute maximum voltage on EXT is 6 V, and the maximum EXT voltage is 2.5 V min, 3.6 V typ, 4.5 V max at VDD=5.0 V and VCS=0 V.
