Overview

The INA200AQDGKRQ1 is an automotive-qualified, high-side current-shunt monitor designed to sense drops across shunts at common-mode voltages from -16V to +80V. It features an integrated open-drain comparator with an internal 0.6V reference and latching capability, providing a compact solution for overcurrent detection in harsh environments.

Why Choose This Part

The device integrates a high-speed comparator with a 500kHz bandwidth amplifier, reducing component count and PCB footprint. Its AEC-Q100 qualification and wide operating temperature range of -40C to 125C ensure reliability in automotive and industrial power applications.

Applications

Electric Power Steering (EPS)
Monitors motor currents to provide feedback for torque control and system diagnostics.
Body Control Modules
Tracks current consumption across various automotive subsystems to detect electrical faults.
Brake Systems
Provides high-speed current sensing for electronic stability and anti-lock braking actuators.
Battery Management Systems
Utilizes the wide common-mode range to monitor charge and discharge cycles in high-voltage vehicle batteries.

Getting Started

To evaluate this part, use a shunt resistor sized for your maximum expected current to ensure the differential voltage stays within the linear range of the amplifier. Connect the open-drain comparator output to a pull-up resistor, and utilize the latch pin if hardware-level fault retention is required.
