The ROHM BV1HD090FJ-CE2 is a single-channel high-side power switch in an 8-SOP-J package, designed for automotive loads up to 9 A.
No external Vcc supply is required — the switch is self-powered from the load rail. The 1:1 input-to-output ratio and On/Off interface simplify integration with a single GPIO.
It is ROHS3 compliant.
Yes, the BV1HD090FJ-CE2 is AEC-Q100 qualified, confirming its suitability for automotive-grade applications.
The typical on-resistance is 90 mOhm, which determines conduction losses at a given load current.
The maximum continuous output current is 9 A, with fixed current limiting as part of the fault protection set.
Yes, the load voltage range of 4.5 V to 36 V covers both 12 V and 24 V automotive electrical systems.
The BD2200GUL- is a functional peer with 100 mOhm Rds(on) and 0.5 A output, but its lower current rating and narrower temperature range (-25°C to 85°C) limit direct substitution in 9 A automotive designs. The BD2062FJ-LBE2 offers 80 mOhm but is a dual-channel USB switch rated for 2.4 A per channel and 85°C max.
