Overview
The ZXCT1012ET5TA is a high-side current monitor and regulator IC manufactured by Diodes Incorporated. It operates within an input voltage range of 2.5 V to 40 V and features a low quiescent current of 2 mA. The device is housed in a TSOT-25 surface-mount package, suitable for compact designs. It supports a differential sense voltage range from 10 mV to 2500 mV across the sensing resistor. The component is designed for robust performance in power management applications requiring precise current monitoring.
Feature Summary
- High-side current sensing capability for accurate monitoring
- Integrated regulation function for load control
- Wide input voltage tolerance up to 40 V
- Compact TSOT-25 surface-mount packaging
Applications
- Battery protection circuits
- Power supply current limiting
- Load switch monitoring
- Overcurrent protection systems
Procurement Notes
Verify the specific suffix ET5TA against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the TSOT-25 package. Cross-reference RoHS compliance status with current environmental declarations before finalizing procurement orders.
Selection Notes
Select this component when high-side monitoring with integrated regulation is required. The 40 V rating suits automotive and industrial bus voltages. The TSOT-25 package offers space efficiency. Verify that the 10 mV minimum sense voltage aligns with the chosen shunt resistor value for the target application current range.
Part Context
This part belongs to the ZXCT101x series of current monitors from Diodes Incorporated. It shares functional similarities with other high-side monitors but distinguishes itself through its specific voltage ratings and regulatory integration. The series is widely used in portable electronics and industrial power systems.
Replacement Considerations
Check for ZXCT1011 or ZXCT1012 variants with different suffixes if package or temperature grade adjustments are needed. Verify pinout compatibility before substitution.
