MH361 Serial

The MH361 is an output driver with Hall sensor for single-coil brush-less DC fans and motors. Beside the magnetic sensor, the device includes an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis, a bi-direction driver for sinking and driving large current load. It also includes locked rotor protection, auto-restart and thermal protection. Placing the device in a variable magnetic field, if the magnetic flux density is larger than Bop, pin DO will be turned to sink and pin DOB will be turned to drive. This output state is held until the magnetic flux density reverses and falls below Brp, then causes DO to be turned to drive and DOB to be turned to sink. MH361 is rated for operation between the ambient temperatures C40C and 125C for the K temperature range. The package is available provided magnetically optimized solutions for most applications. Package VK is a four-lead ultra mini SIP for through-hole mounting. also the Thermal shut-down function is integrated as well for better protection. The package type is in a Halogen Free version has been verified by third party Lab.

Focus on Hall Effect Technology, and get into Consumer/Industrial/ Automation/Automotive field not only IC but also Sensor module applications. Visitor:1320397 times
