OB2506NCP

OB(On-Bright Elec) · Battery Management ICs · SOP-8

OB2506NCP from OB(On-Bright Elec), in a SOP-8. 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 FB input Feedback input pin; the PWM duty cycle is determined by the voltage level into this pin and the current-sense signal at CS (5V open loop voltage, 15kΩ internal pull-up).
2 VCC power_in Power supply pin with recommended operating range 8 to 25V, UVLO exit 18.2V typ and enter 7.0V typ, absolute maximum 28V.
3 AUX input Voltage feedback from the auxiliary winding via a resistor divider reflecting output voltage, with output OVP threshold of 3.0V typ and absolute maximum of 7V.
4 CS input Current sense input where external sense resistor Rs sets the CC point and output power, with 300ns leading edge blanking and absolute maximum of 7V.
5 Drain passive Drain of the internal 600V power MOSFET (Rdson 8Ω for OB2506N), connected to pin 6.
6 Drain passive Drain of the internal 600V power MOSFET (Rdson 8Ω for OB2506N), connected to pin 5.
7 GND power_in Ground pin.
8 GND power_in Ground pin.
