Hall IC Series / Hall IC(Latch type)
Bipolar Detection Hall ICs
BU52001GUL, BU52011HFV, BU52021HFV, BU52015GUL, BU52025G, BU52051NVX, BD7411G
٨Description
The bipolar Hall ICs are magnetic switches that can operate both S-and N-pole , upon which the output goes from Hi to Low. In addition to regular single-output Hall ICs, We offers a line up of dual-output units with a reverse output terminal (active High).
٨Features
1) Bipolar detection
2) Micropower operation (small current using intermittent operation method)(BD7411G is excluded.)
3) Ultra-compact CSP4 package (BU52001GUL,BU52015GUL)
4) Ultra-Small outline package HVSOF5 (BU52011HFV,BU52021HFV)
5) Ultra-Small outline package SSON004X1216 (BU52051NVXV)
6) Small outline package (BU52025G,BD7411G㧕
7) Line up of supply voltage
For 1.8V Power supply voltage㧔BU52011HFV,BU52015GUL,BU52051NVX)
 For 3.0V Power supply voltage (BU52001GUL)  For 3.3V Power supply voltage (BU52021HFV,BU52025G)  For 5.0V Power supply voltage (BD7411G)
8) Dual output type (BU52015GUL)
9) High ESD resistance 8kV(HBM)
٨Applications
Mobile phones, notebook computers, digital video camera, digital still camera, white goods etc.
