CQ-236B
Product:Sensor ICs > Current Sensors
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.
