Allegro MicroSystems has introduced three new ICs aimed at improving motor control and thermal management in e-mobility and industrial automation: the ACS37035 and ACS37630 current sensors, and the A89347 fan driver IC.
These solutions deliver improved precision, efficiency, and system reliability across applications such as robotics, industrial motors, EV traction inverters, and battery cooling systems.
“Our latest motor control and thermal management solutions reflect Allegro’s commitment to delivering innovative technology that enhances efficiency and performance across automotive and industrial applications,” said Ram Sathappan, Vice President of Global Marketing and Applications at Allegro. “We are excited to highlight these products as forward-looking solutions for simplifying design, improving system efficiency, and empowering our customers to innovate and deliver exceptional value.”
Key features of the new ICs include:
- ACS37035 Current Sensor features a 1 MHz bandwidth and 0.45 µs typical response time. Its differential sensing and 4 mA/Gauss CMRR offer excellent noise immunity. With ±3% sensitivity error over temperature and low offset voltage, it enables tighter control loops and increased motor efficiency. The ACS37035 is ideal for load detection, motor control, and switch-mode power supplies.
- ACS37630 Current Sensor is designed for U-core current sensing and delivers up to 250 kHz bandwidth with a 1.6 µs response time. Its vertical Hall effect sensing simplifies system integration with U-core magnets and eliminates the need for bulky C-cores. Automotive Grade 0 qualified (–50 to +150°C), it delivers contactless current sensing with ±0.7% sensitivity and a ±5 mV offset.
- A89347 Fan Driver IC AEC-Q100 qualified IC ensures reliable performance in automotive environments. A three-phase, sensorless BLDC fan driver offering sinusoidal drive and closed-loop speed control to minimize noise and vibration. EEPROM-configurable speed curves and integrated low-power standby (10 µA) allow efficient thermal management for EV seat and battery-cooling fans. The IC is AEC-Q100 qualified.
All three products will be supported with evaluation boards and design resources. The ACS37035 and ACS37630 are available now; the A89347 will be available in summer 2025.
