BV1HJ045EFJ-C & BV1HL045EFJ-C AEC-Q100 PMICs ROHM Semiconductor BV1HJ045EFJ-C and BV1HL045EFJ-C AEC-Q100 PMICs (Power Management ICs) are high-side switches, with an integrated CMOS control unit and power MOSFET mounted on a single chip. These single N-channel devices feature a diagnostic output function for abnormality detection. The BV1HJ045EFJ-C and BV1HL045EFJ-C have a built-in overcurrent limit function, thermal shutdown protection function, open load detection function, low power output-OFF function, and short-to-VCC detection function. The BV1HJ045EFJ-C has an overcurrent limit of 5.0A to 12.0A. The BV1HL045EFJ-C has an overcurrent limit of 2.5A to 5.5A.
