FSA4480UCX

The FSA4480UCX is a high-performance, single-channel, high-side current sensor from ON Semiconductor. It is designed to provide accurate and reliable current sensing in a wide range of applications, including battery management systems, motor control, and power management.

Description:

The FSA4480UCX is a monolithic, precision, current sensing amplifier that can operate from a supply voltage as low as 2.7V. It features a gain of 20V/V, which allows for a wide input current range and high accuracy. The device also includes an internal shunt resistor, which eliminates the need for an external shunt resistor.

Features:

• Single-channel, high-side current sensing
• Wide input current range (up to ±50A)
• High accuracy (±1.5%)
• Low supply voltage (2.7V to 5.5V)
• Internal shunt resistor
• Small package (DFN-10)
• Wide operating temperature range (-40°C to +125°C)

Applications:

• Battery management systems (BMS)
• Motor control
• Power management
• Energy harvesting systems
• Electric vehicles (EVs)
• Solar panel monitoring
• Uninterruptible power supply (UPS) systems

In summary, the FSA4480UCX is a high-performance current sensing amplifier that offers high accuracy and a wide input current range. Its small package and low supply voltage make it suitable for a wide range of applications, including battery management systems, motor control, and power management.
