Other Notes
Standby function
Pin 5 in this IC is the standby pin, and applying a voltage of 2.0 V or
higher will activate this function. The pin 5 influx current for an
applied voltage of 5 V will be about 240 A.
ISTB =
5 V – 1.4 V
= 240 A
15 k
Insert an external current limiting resistor (RSTB) if it is necessary to
limit this influx current when using a microcontroller.
If this input voltage is applied by a circuit or device other than a
microcontroller, calculate the value for RSTB from the following
formula such that the pin 5 influx current due to the applied VSTB is
under 500 A.
RSTB =
Applied voltage (VSTB) – 1.4 V
– 15 k
500 A
