Description

The ZXCT1080Q and ZXCT1081Q are high side current sense monitors with a voltage output and a fixed gain of 10. Using this device eliminates the need to disrupt the ground plane when sensing a load current.

The wide input voltage range of 60V and 40V, respectively, down to as low as 3V make it suitable for a range of automotive applications with 60V and 40V load dump withstand capabilities.

The separate supply pin (V_CC) allows the device to continue functioning under short circuit conditions.

The ZXCT1080Q and ZXCT1081Q have an extended ambient operating temperature range of -40°C to 125°C enabling it to be used in a wide range of automotive applications including.

The ZXCT1080Q and ZXCT1081Q have been qualified to AEC-Q100 Grade 1 and are Automotive Grade supporting PPAPs.
