PLANO, Texas–(BUSINESS WIRE)–Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announced a series of bidirectional current monitors based on a high-stability zero-drift architecture. These devices are capable of accurately measuring very low sense voltages across a wide range of common-mode voltages. Key applications include laptop PCs, battery chargers, industrial servos, servers, power supply racks in server farms, and robotic systems.
Consisting of six different variants, the DIODES™ ZXCT199 series of current monitor devices each feature a precision chopper stabilized op-amp for high accuracy operation. Their low offset voltage enables current sensing with maximum drops across shunts as low as 10mV full-scale. This allows high currents to be measured via inexpensive, low-value shunt resistor components.
The ZXCT199 series are voltage output type devices, and are available in three fixed voltage gain options in 50V/V, 100V/V, and 200V/V. These devices can measure voltages across shunts at common-mode voltages from -0.1V to 26V, independent of the supply voltage.
The new current sensors from Diodes have an operational temperature range of -40°C to 125°C, exhibiting minimal gain error across this. For the A and B versions, the maximum gain error over temperature is ±1.0%, while for the C version, it is ±0.8%. Their offset voltage levels are a maximum of ±150μV for the A version, ±100μV for the B version, and an ultra-low ±80μV for the highest precision C version. All variants can be powered via a 2.7V to 26V supply, giving them greater application flexibility. A maximum supply current of just 100μA is drawn.
