UH276

反向保护二极管、输出钳位二极管在开关过程中的峰值输出电压切换、优良的滞后性

■ DESCRIPTION

The is a Latch-Type Hall Effect sensor with built-in complementary output drivers. It’s designed with internal temperature compensation circuit and built-in protection diode prevent reverse power fault. The application is aimed for brush-less DC Fan.

The UH276 Outputs operate as the Hysteresis Characteristics. The Outputs alternately ON and OFF when either the magnetic flux density larger than threshold BOP or the magnetic flux density lower than BRP.

■ FEATURES

* Widen Power Supply range from 3V ~ 20V.

* On-chip Hall sensor with excellent hysteresis.

* Open Collector outputs had the sinking capability up to 400mA.

* Output Clamping Diodes reduce the peak output voltages during switching.

* Build-in reverse protection diode.
