ZXCT180Q中文资料Automotive, 26V, 400kHz Bandwidth Uni-Directional, Low-Side and High-Side Current Monitor数据手册Diodes规格书

描述 Description

The ZXCT180Q is automotive AEC-Q qualified uni-directional current shunt monitor which is designed to be a cost-effective solution to deal with 26V common-mode in a smaller supply voltage range 2.7V to 5.5V powering the device.


The ZXCT180Q supports the small-signal bandwidths as high as 400kHz at 20V/V gain and fast large-signal slew rates of 2V/µs. This ability can be used to detect rapid changes in the sensed current and fast response to the output so that these features make the ZXCT180Q a good choice for applications such as low-side motor control and the system fault current detection.


OUT pin is a voltage proportional to the load current. Based on OUT pin configurations, ZXCT180 has Pinout A and B as a flexibility for users to choose a proper one for PCB layout. In addition, this device has four fixed voltage gain options in 20V/V, 50V/V, 100V/V, and 200V/V. It can measure voltage across shunts at common-mode voltages from -0.3V to 26V, independent of supply voltage with a maximum supply current of 370μA. All versions are AEC-Q100 grade 1 temperature range, -40°C to +125°C, and are offered in the SOT25 package.
