Toshiba Corporation has announced the launch of a brushed motor pre-driver IC for automotive applications, TB9052FNG. Sample shipments will start in August, with mass production scheduled to start in March, 2015.
Safety-critical automotive systems, such as electric power steering (EPS), must meet the requirements of ASIL-D, the highest automotive safety integrity level prescribed in ISO 26262, “Road Vehicles – Functional Safety.” Toshiba’s new brushed motor pre-driver IC integrates essential functions, including a pre-driver circuit and motor current detection circuit, plus various failure detection circuits for higher functional safety.
Toshiba has also carried out a range of functional safety analyses to simulate various system failures and will provide customers with documentation to support safety analysis and design.
