The MAX9641 is dual, low-power Hall-effect sensor. Using two sensors spaced apart on the die, it detects the direction and frequency of a magnetic field. The user can select one of three preset thresholds and one of three sampling rates to minimize power dissipation. The MAX9641 is offered in a 6-bump WLP (1.2mm x 1.7mm x 0.6mm). * 1.7V to 5.5V Supply Voltage Range * Ultra-Low Supply Current * Adjustable Thresholds * Adjustable Duty Cycle * Direction Indicator * CMOS Output Eliminates the Need for an External Pull-Up Resistor * Tiny 1.2mm x 1.7mm, 6-Bump WLP * -40°C to +125°C Temperature Range
