Diodes Incorporated ZXCT21xQ AEC-Q Current-Shunt Monitors

Diodes Incorporated ZXCT21xQ AEC-Q Current-Shunt Monitors feature a lineup of automotive AEC-Q-qualified high-precision current-shunt monitors. These Diodes Incorporated ZXCT21xQ modules are designed for current measurement in the automotive industry. With a range of gain options, these monitors offer accuracy when measuring low-voltage drops as small as 10mV across compact shunt resistors, ensuring minimal error. This enables precise measurement of large currents and mitigates power loss typically associated with measurements taken at common-mode voltages ranging from -0.3V to 26V.
