SDC141

Switch Hall IC Datasheet SDC141 General Description Features The SDC141 is a lock-type switch hall IC. It’s composed of Tpower reverse protection circuit, high stable voltage regulator, hall voltage generator, a differential amplifier, Nschmitt trigger and open collector output. Change of Emagnetic field can be converted into digital signal. It can be used for brushless DC three-phase motors, brushless L DOCUMDC fans, and speed measurement occasions.  Operating voltage: 4V to 24 V  Built-in temperature compensation circuit  Built-in power reverse protection  Operating temperature: -55°C~150°C  Open collector output  20mA(MAX) output sink current  Operating speed: 0~100kHz above  Package：TO-92S、SOT23-3 Applications  Three-phase brushless DC motor  Brushless DC fan  Tachometer  Speed measurement CONFIDENTIATO-92S SOT-23-3 SDC Figure 1.
