Bipolar Hall Effect Switch Ics CYD9802A, Power Supply: 2.5V -18V, Power Supply current: 25mA

The CYD9802A is designed for magnetic actuating using a bipolar magnetic field. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. This Hall Effect IC is suitable for DC brushless fan applications. The supply voltage range is from 2.5V to 18V and the maximum output current is 25mA. This Hall Effect switch IC integrates the sensor, pre-amplifier with dynamic offset cancellation and hysteresis comparator in single chip.
