New high side switch ICs with user-definable protection

20-11-2020 | ROHM Semiconductor | Automotive Technologies

ROHM has revealed the development of a new family of four AEC-Q100 qualified high side switch ICs aimed at the automotive market. Offered in both one and two-channel variants with RDS(on) ratings of 45mOhm, 70mOhm and 90mOhm, these IPDs comprise multiple protection functions, ranging from OCP and TSD to OLD and UVLO, as well as a diagnostic output function for error detection.


Also, the 70mOhm BV2HD070EFU-C and 45mOhm BV2HD045EFU-C/BV2HC045EFU-C 2ch high side switches offer variable OCD and OCD mask functions that enable users to set limits for the overcurrent threshold and time to attain the optimum overcurrent protection for a given load. Built-in double error flags make it possible to differentiate between two different fault types for each channel output.


“These smart IPDs allow users to develop optimised solutions for resistive, inductive and capacitive loads in automotive applications, such as automotive ECUs and vehicle cabin climate control,” stated Nobuyuki Ikuta, senior solutions marketing manager at ROHM USA.
