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 ZCL™ 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.

Voltage Tracker S-19720 series
Low offset voltage
Ultra-compact package
Low current consumption
Voltage Tracker that contributes to high-accuracy sensing
The industry’s lowest offset voltage of ±5mV helps keep the power supply voltage of the off-board ratiometric sensor equal to the reference voltage (Vref) of the AD converter (ADC) handling ECU measurements, raising sensor reading accuracy. The voltage tracker with its 36V input and 50mA output current is housed in an HSNT-6(2025), the industry’s smallest package. The S-19720 helps further reduce the footprint of automotive devices.
