BM1P067FJ-E2

ROHM Semicon · AC-DC Controllers & Regulators · SOIC-8

BM1P067FJ-E2 from ROHM Semicon, in a SOIC-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 N.C unconnected Non-connection pin with no internal connection, per the pin table.
2 FB input Feedback signal input pin, with an internal pull-up of 22 kΩ to 38 kΩ (30 kΩ typ.).
3 CS input Primary current sense pin; overcurrent detection voltage is 0.380 V to 0.420 V (0.400 V typ.) at Ton = 0 µs, with 250 ns typ. leading edge blanking.
4 GND power_in Ground pin for the IC, listed as I/O in the datasheet pin table and carrying the ESD diode to GND only.
5 OUT output External MOS drive pin that drives the external switching MOSFET.
6 VCC power_in Power supply input pin; the stated operating supply range is 8.9 V to 26.0 V, and the block diagram shows VCC overvoltage protection at 27.5 V.
7 N.C. unconnected Non-connection pin with no internal connection, per the pin table.
8 VH input Start circuit pin; VH is rated up to 600 V and the built-in start circuit withstands 650 V.
