BLH301 Datasheet | BELLING

Hall Effect Switch High Sensitivity /Low Power Hall Effect Switch --BLH301 BLH301 Hall-effect sensor is a temperature stable, stress-resistant, Low Tolerance of Sensitivity micro-power switch. Superior high-temperature performance is made possible through a dynamic offset cancellation that utilizeschopper-stabilization. This method reduces the offset voltage normally caused by device over molding, temperature dependencies, and thermal stress. BLH301 is special made for low operation voltage, 1.5V, to active the chip which is includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, CMOS output driver. Advanced CMOS wafer fabrication processing is used to take advantage of lowvoltage requirements, ponent matching, very low input-offset errors, and small ponent geometries. This device requires the presence of omni-polar magnetic fields for operation. The package type is in a Halogen Free version has been verified by third party Lab. - Features - Omni polar, High sensitivity switch hall IC - Operation from 1.5V to 6v - Ultra low power consumption at 2.2u A (Avg.) - High ESD protetion, HBM(HBM) 4000V - Operation frequency : 25Hz Shanghai Belling Corp., Ltd.
