Overview

The NCV213RSQT2G is an AEC-Q100 qualified current sense amplifier designed for precise current monitoring in automotive and industrial power systems. It features a rail-to-rail output and can handle common-mode voltages up to 26V, making it suitable for both high-side and low-side sensing applications. With a low supply current of 40uA typical, it is optimized for power-sensitive designs requiring high accuracy.

Why Choose This Part

This amplifier offers a 90 kHz bandwidth and a 1V/us slew rate, providing a balance of speed and stability for most power management tasks. Its AEC-Q100 qualification and PPAP capability ensure high reliability in harsh automotive environments across a wide temperature range of -40C to 125C.

Applications

Automotive Battery Management
Monitoring charge and discharge currents in 12V vehicle systems to ensure battery health and SOC accuracy.
Motor Control Feedback
Providing real-time current feedback for brushless DC or stepper motor drivers in industrial automation.
Telecom Power Distribution
Measuring current flow in 24V DC power rails for system health monitoring and overcurrent protection.
LED Lighting Control
Implementing constant current regulation in high-brightness LED strings for automotive lighting.

Getting Started

To evaluate this part, design a PCB with a low-resistance shunt resistor and keep traces symmetrical to minimize offset errors. Ensure the VDD supply (2.2V to 26V) is decoupled with a 0.1uF ceramic capacitor placed close to the SC70-6 package pins.

Also Consider

INA213 TITexas Instruments - Offers a similar pinout and gain profile but is the non-automotive industrial standard equivalent.
