微功耗霍尔开关美容保湿器用霍尔，霍尔集成电路 YH13S_霍尔集成电路

Hall  effect  sensor  IC  is  fabricated  from  mixed  signal
CMOS  technology.  It  incorporates  advanced  chopper-stabilization  techniques  to
provide  accurate  and  stable  magnetic  switch  points.
The  circuit  design  provides  an  internally  controlled  clocking  mechanism  to
cycle  power  to  the  Hall  element  and  analog  signal  processing  circuits.  This  serves
to  place  the  high  current-consuming  portions  of  the  circuit  into  a  “Sleep”  mode.
Periodically  the  device  is  “Awakened”  by  this  internal  logic  and  the  magnetic  flux
from  the  Hall  element  is  evaluated  against  the  predefined  thresholds.  If  the
flux  density  is  above  or  below  the  Bop/Brp  thresholds  then  the  output  transistor  is
driven  to  change  states  accordingly.  While  in  the  “Sleep”  cycle  the  output  transistor
is  latched  in  its  previous  state.  The  design  has  been  optimized  for  service  in
applications  requiring  extended  operating  lifetime  in  battery  powered  systems.
The  output  transistor  of  the  will  be  latched  on  in  the  presence  of  a
sufficiently  strong  South  or  North  magnetic  field  facing  the  marked  side  of  the
package.  The  output  will  be  latched  off  in  the  absence  of  a  magnetic  field.
Features：
·  2.2  V  to  6.0  V  battery  operation
·  High  sensitivity  and  high  stability  of  the  magnetic  switching  points
·  High  resistance  to  mechanical  stress
·  Digital  output  signal
·  Switching  for  both  poles  of  a  magnet  (omnipolar)
