Hallwee HAL246R全極低功耗霍爾開關(guān) 高頻率磁控管 OPEN DRAIN推挽式輸出，Hallwee成立于2011年，專做霍爾開關(guān)，品牌HALLWEE，為解決客戶對(duì)其品質(zhì)的擔(dān)憂，公司尋找國(guó)內(nèi)外極其成熟的霍爾元件芯片晶圓，并輔以國(guó)內(nèi)測(cè)試封裝，成為以低成本/高品質(zhì)/高性價(jià)比的霍爾元件（霍爾開關(guān)）優(yōu)質(zhì)供應(yīng)商，短短幾年就在國(guó)內(nèi)市場(chǎng)占領(lǐng)一席之地，并且銷量每年都在穩(wěn)定增漲。HAL246R霍爾開關(guān)

　　HAL246R 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 utilizes chopper-stabilization. This method reduces the offset voltage normally caused by device over molding， temperature dependencies， and thermal stress. is special made for low operation voltage， 1.7V， 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 low-voltage requirements， component matching， very low input-offset errors， and small component 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.
