ZXCT21xQ: High-Precision Current Shunt Monitors for EVs

Diodes Incorporated (Nasdaq: DIOD) has launched a new series of high-precision current shunt monitors called ZXCT21xQ. These monitors are specifically designed for electronic components distributors and are ideal for measuring small sensing voltages within a wide range of common-mode voltages found in electric vehicles (EVs).

The ZXCT21xQ series offers accurate current sensing for various automotive applications such as brushless DC (BLDC) motor controllers, electric compressors, high-power DC-DC converters, on-board chargers (OBCs), battery management systems (BMSs), ADAS power supplies, and wireless phone chargers.

Key features of these monitors include zero-drift cores with low offset voltage and gain errors, allowing for precise current sensing with minimal voltage drop. This enables the use of small sensing resistors, reducing power losses during measurement. The series also boasts low static current consumption, minimizing overall power consumption.

With a rail-to-rail common-mode sensing voltage range of 0-26V and bidirectional current measurements, the ZXCT21xQ series provides flexibility for high-side and low-side current monitoring. It offers six voltage gain options and three accuracy versions, allowing for customization based on specific requirements.

All devices in the ZXCT21xQ series adhere to AEC-Q100 Grade 1 specifications, ensuring high-quality performance. Manufactured in IATF 16949 certified facilities and supporting PPAP documentation, these monitors meet industry standards. They operate reliably within a temperature range of -40°C to +125°C and come in the popular SOT363 package, making them easy to integrate for the electronic components industry.
