Title
Ultra-High Sensitivity Small AI-Shell Current Sensor

Applications
Power Conditioners

Description

Multistring panels for photovoltaic power generation have recently been in high demand. With this trend, the power conditioner requires a higher sensitivity current sensor for MPPT, (Maximum Power Point Tracking), control.

Asahi Kasei Microdevices Corporation, (AKM), has developed a new current sensor. The CQ-236B achieves higher sensitivity compared to an AI-Shell current sensor, the CQ-206B.

● High Sensitivity is Achieved

The CQ-236B is a 0 to 25A low-side current detection IC achieving much higher sensitivity than the former current sensor, the CQ-206B , (0 to 45A). It achieves a wide dynamic range despite its small current range, (0 to 25A).

● Temperature Characteristics are Improved

Temperature drift from current sensitivity is improved by 50% compared with the CQ-206B.

● High Layout Potential that Needs No Insulated Power Supply

The CQ-236B runs on a single 5V power supply. This gives greater layout flexibility since it does not need an insulated power supply.
