TYPICAL APPLICATIONS
TYPICAL APPLICATIONS
The 33897 can be used in applications where the module
includes a regulator that has the capability of going into Sleep
mode by having an Enable pin. See Figure 8. When the
module’s regulator is in Sleep mode, the module is turned off.
The module waits for a defined wake-up voltage level on the
bus. This wake-up voltage will activate the CNTL line, which
enables the regulator and turns the module back ON. This
feature allows the module to be more energy efficient since
the current consumption is significantly lowered when it goes
into sleep mode.
