ROHM has announced the development of a new family of four AEC-Q100 qualified high side switch ICs targeting the automotive market. Available in both 1- and 2-channel variants with RDS(on) ratings of 45m?, 70m? and 90m?, these IPDs (Intelligent Power Devices) incorporate multiple protection functions, ranging from overcurrent protection (OCP) and thermal shutdown (TSD) to open load detection (OLD) and under voltage lockout (UVLO), as well as a diagnostic output function (ST) for error detection.

In addition, the 70m? BV2HD070EFU-C and 45m? BV2HD045EFU-C/BV2HC045EFU-C 2ch high side switches feature variable OCD and OCD mask functions that allow users to set limits for the overcurrent threshold and time to achieve the optimum overcurrent protection for a given load. Built-in double error flags make it possible to distinguish between two different fault types for each channel output.

“These smart IPDs allow users to develop optimized 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.
