ICs ideal for Electric Power Steering Motors
Electric Power Steering (EPS) uses an electric motor to assist the operation of the steering wheel. Compared to the conventional hydraulic assist system, EPS improves fuel efficiency because it does not require an engine-powered oil pump. Additionally, EPS is indispensable for advanced driver assistance such as Autonomous and Lane Keeping Assist, which can be precisely controlled by an electric motor.
ABLIC offers ICs ideal for EPS motors that support "A" (Autonomous) in CASE. ABLIC offers a comprehensive range of products: such as Zero Crossing Latch Hall effect ICs which operate ideally in BLDC motors, high-accuracy Voltage Trackers for torque sensor power supplies, LDOs with built-in watchdog timers for monitoring MCUs, and battery monitoring ICs that monitor 12V auxiliary batteries for abnormal voltages.
