MH251 All-Polar Hall Switch
Model: | Category: Hall Sensor IC
Product Overview
The MH251 is an ultra-sensitive all-polar Hall-effect switch IC that responds to either North or South magnetic poles. It is designed for battery-powered and low-voltage applications. Key Features: - Ultra-wide voltage range: 1.8V to 5.5V - All-polar sensitivity: works with either pole - Nano-power consumption for battery operation - Digital output with built-in hysteresis - Omnipolar magnetic switching - High ESD protection - SOT23 and TO-92 package options Typical Applications: - Battery-powered devices - Wearable electronics - Portable medical instruments - Wireless sensors - Simple contactless switches - Mobile phones and accessories The all-polar design eliminates the need for magnetic pole orientation, simplifying assembly and reducing production costs.
