BH1751FVI
VCC
BH1751FVI has power on reset (POR) function. POR is to reset all register and flip flop when VCC Power supplies.
There are some cautions about power on and down sequence seeing in below.
① Power on time : t1
② Power off time : t2
* I
*”active state” is that BH1751FVI works and accept I
More than 2ms is need to active BH1751FVI after VCC supplies more than 2.0V from VCC is less than 0.4V.
More than 1ms (VCC < 0.4V) is need to active BH1751FVI.
