Descriptions:

The MAX961ESA+T is designed for high-side current sensing in applications such as battery monitoring, power management, and motor control. It features a wide input common-mode voltage range, allowing it to operate in systems with varying supply voltages. The device includes an integrated precision amplifier with selectable gain settings, eliminating the need for external gain-setting resistors in some configurations.

Features:

• High-Side Current Sensing: Monitors current without disrupting the ground path.
• Wide Input Voltage Range: Supports operation from +0V to +28V.
• Adjustable Gain: Configurable gain via external resistors for flexibility.
• Low Offset Voltage: Ensures accurate current measurement.
• Rail-to-Rail Output: Maximizes dynamic range.
• Low Power Consumption: Suitable for battery-powered applications.
• Integrated Comparator: Provides overcurrent detection capability (in some variants).
