FAQs
What is ZXCT1041?
The ZXCT1041 is a precision high-side current sense monitor designed by Diodes Incorporated. It is used for accurately monitoring current flow in high-side applications, such as battery management, power supplies, and motor control systems.
How Does ZXCT1041 Work?
The ZXCT1041 operates by measuring the voltage drop across an external shunt resistor in the high-side current path. It amplifies this voltage drop and provides a proportional output voltage or current that represents the load current. The monitor features high accuracy and low offset voltage for precise current measurements.
How Many Pins does ZXCT1041 have and What are the Functions of the Pinout Configuration?
The ZXCT1041 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VSENSE: Sense voltage input for monitoring the high-side current.
- GND: Ground connection.
- VREF: Reference voltage output for calibration.
- V+: Positive power supply voltage input.
- VOUT: Output voltage proportional to the sensed current.
- NC: No connection.
- VTEMP: Temperature sensing input.
What are the Pros and Cons of ZXCT1041?
Pros:
- High Accuracy: Provides precise current monitoring for critical applications.
- High-Side Sensing: Enables monitoring of current flow without affecting ground reference.
- Low Offset Voltage: Ensures accurate measurements with minimal error.
- Compact Package: The 8-pin SOIC package offers space-efficient integration.
- Temperature Sensing: Includes temperature sensing capability for enhanced system monitoring.
Cons:
- External Shunt Resistor: Requires an external shunt resistor for current sensing, adding to component count.
