4.
The MB3790 outputs a reset signal when the power supply momentarily goes down or its voltage sags for 5
μ
s or
more. The set time before this reset signal is output can be extended by connecting a capacitor to the V
SENSE
pin.
Adjusting the Supply Voltage Detection Level Set time
5.
The MB3790 has its ALM1 and ALM2 pin specifications matched to the BVD2 and BVD1 pin specifications of the
JEIDA Memory Card Guideline Ver. 4. Therefore, the ALM1 and ALM2 pins can be connected directly to the BVD2
and BVD1 pins.
