更新时间：2026-10-18 17:10:31 |
OH37 Unipolar Hall Effect Switch ICOH37 Unipolar Hall Effect Switch IC General Description: Part No. OH37 Operate temperature: -40～85℃ Package:3000pcs/reel OH37 Hall switch IC is internally consisted by reverse voltage protection device, voltage regulator, hall voltage generator, a differential amplifier, Schmitt trigger and the open collector output level, which can change magnetic field signal into digital voltage output. OH37, with the feature of small size (SOT23 package) and stable performance in -40～85℃, have been widely used in various fields as a non-contact switch IC. Features 4.5V to 24V DC operation voltage Open-Collector pre-driver 25mA maximum sinking output current.

Hall ICs with Build-in Resistor are not necessary to add one, for example OH921. 2) Avoid reversing the power supply (Vcc) and the output (Vout) as well as no overload use. Be careful of the burn and damage caused by instant large current and instantaneous high voltage. 3) The Protection circuit should be added in the test circuits of hall ICs, such as large capacitor and a voltage stabilizing diode, which could absorb the effects of the external circuit and power fluctuation. 4) Try to minimize the mechanical stress applied to the device and leads during the installation, especially on the pins where close to the root of the device when bending shaping etc. 5) Strictly regulate the welding temperature and time. When manual welding, the temperature of soldering iron shall not exceed 260℃and time should be less than 3 seconds. 6) When designing, please fully consider the influence factors of temperature, magnetic field attenuation, the movement way, etc. OH41 Hall effect Latch ICOH44 Unipolar Hall Effect Switch IC 1116-090-463 DEUBLIN 江苏现货供应.江苏现货供应1205-000-025 DEUBLIN旋转接头 AX115CE磁性开关现货ES008征能钳形电流互感器 |
OH41 Hall effect Latch ICOH41 Hall effect Latch IC General Description Part Number: OH41 Operate temperature: -40～150℃ Package: 1000pcs/bag OH41 Hall effect Latch Switch IC is composed of a reverse protector, voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger and an open-collector output on a single silicon chip. It can convert the magnetic field signal into digital voltage output, in response to N and S alternating magnetic field.
