DP3367C

Shenzhen Developer Microelec · Battery Management ICs · SOP-8

DP3367C from Shenzhen Developer Microelec, 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 Ground reference for the internal circuitry of the chip.
2 VDD power_in Supply pin for the internal circuitry. Recommended operating range 9-40V; UVLO turn-on typ 13.4V, turn-off typ 7.8V, OVP typ 43V. Startup current ~3uA typ (10uA max).
3 FB input Feedback input pin. PWM output frequency and duty cycle are set by FB together with CS. FB open-circuit voltage 5.7V, short-circuit current typ 150uA, overload threshold 3.5V, internal pull-down ~30k.
4 CS input Inductor peak current sense input. Cycle-by-cycle current limit VOCP typ 0.65V (at Duty=0). Leading-edge blanking typ 400ns, internal impedance ~40k.
5 Drain output Drain of the integrated high-voltage power MOSFET (650V BVdss, Rds(on) ~0.95Ω, 4.5A). Pins 5-8 are internally tied together to increase current/thermal capacity.
6 Drain output Drain of the integrated high-voltage power MOSFET (650V BVdss). Commoned with pins 5, 7, 8.
7 Drain output Drain of the integrated high-voltage power MOSFET (650V BVdss). Commoned with pins 5, 6, 8.
8 Drain output Drain of the integrated high-voltage power MOSFET (650V BVdss). Commoned with pins 5, 6, 7.
