The MAX472EPA is a high-precision, high-side current-sense amplifier from Maxim Integrated. This device is designed to monitor the current flowing through a shunt resistor placed in the high side of a power supply or in any current path, providing a voltage output proportional to the current. It is a critical component for systems that require accurate current monitoring and control, such as battery chargers, power management systems, and automotive applications.
Key Features
- High-Side Measurement: Allows for the monitoring of the load current without interfering with the ground path.
- Wide Supply Voltage Range: Operates from 4.5V to 36V, making it suitable for a variety of applications.
- Low Quiescent Current: Consumes minimal power with a quiescent current of only 100µA, enhancing system power efficiency.
- High Accuracy: Provides precise current measurement with an accuracy of ±1.5% max over the entire temperature range.
- Adjustable Gain: Offers an adjustable voltage output gain by selecting external gain-setting resistors.
Applications
- Battery charging and management systems
- Power supply monitoring
- Automotive battery monitoring
- Overcurrent and undercurrent detection
- Portable devices
