Mingjiada Electronics Supply Allegro ACS770, ACS758, ACS723 And ACS37100 Current Sensors

With the rapid development of new energy electric vehicles, industrial automation and high-power-density power supply systems, precise, safe and efficient current sensing has become a core requirement in circuit design. Shenzhen Mingjiada Electronics Co., Ltd.—as a professional distributor of electronic components—has long provided a stable supply of Allegro’s full range of high-precision current sensors. Leveraging high-quality supply chain resources and genuine product quality assurance, the company offers one-stop procurement solutions to global customers, enabling precise current sensing and efficient control in a wide range of electronic devices.

Allegro Current Sensors: The Industry Benchmark for High-Precision Sensing
Allegro current sensors combine electrical isolation, lossless operation and ultra-high precision, enabling the highest efficiency and power density in compact systems. Designed specifically for electric vehicle traction inverters, on-board chargers (OBCs), DC-DC converters, solar inverters and industrial power systems. Featuring isolation ratings of up to 5 kVRMS, ultra-low conductor resistance as low as 0.1 mΩ, and a bandwidth of up to 5 MHz compatible with GaN/SiC power devices, they effectively replace traditional shunt-amplifier combinations, simplifying layout and enhancing safety.

Mingjiada Electronics offers a comprehensive range of Allegro current sensor products, spanning from classic Hall-effect to advanced TMR (Tunnel Magnetoresistance) technologies. Our standard stock includes, but is not limited to, the following core series:

ACS770 Series: Representative models include ACS770LCB-050B-PFF-T and ACS770LCB-100B-PFF-T; Featuring a built-in 100μΩ ultra-low-resistance sensing conductor, integrated digital temperature compensation and shielding technology, a typical bandwidth of 120kHz, and support for a 4.5–5.5V single supply, these are suitable for a wide range of industrial and automotive current sensing applications.

ACS758 Series: Popular models include the ACS758LCB-050B-PFF-T and ACS758ECB-200B-PFF-T; these are high-current sensing models with an internal resistance as low as 100μΩ, an accuracy of ±1.2%, a bandwidth of 120kHz, and an operating temperature range of -40°C to 150°C. They are widely used in motor control, BMS and industrial automation.

ACS723 Series: Key models include the ACS723KMATR-40AB-T and ACS723LLCTR-10AB-T; featuring a compact package, these support current sensing from 10 to 40A with analogue signal output and a supply voltage of 3.3V to 5V. They offer high immunity to interference and are suitable for space-constrained consumer electronics and small industrial equipment.

ACS709 / ACS712 series: such as the ACS709LLFTR-35BB-T and various classic entry-level ACS712 models; the preferred choice for low-power, general-purpose or low-current sensing applications, suitable for small power supplies, load sensing, household appliances and overcurrent protection.

ACS37100 Series (TMR Technology): Core models such as the ACS37100LLUATR; utilising TMR technology, with a bandwidth of up to 10MHz and excellent accuracy, supporting bidirectional current sensing, making it an ideal choice for GaN/SiC high-frequency switching platforms such as new energy vehicle OBCs and DC-DC converters.

Next-generation and core-less series such as CT45x and ACS37x: Models including the CT455, CT452 and ACS37610 offer bandwidths of 1 MHz and above, contactless or core-less designs, high common-mode rejection ratio and advanced diagnostic functions, targeting high-reliability clean energy, EV charging and high-end industrial frequency conversion applications.
