Operation mode
There are three operation modes of the HT9032. They are power down mode, partial power up mode,
and power up mode. The three modes are classified by the following conditions:
Modes
Conditions
Current
Consumption
Power down
PDWN= 1 and RTIME= 1
<1 A
Partial power up
PDWN= 1 and RTIME= 0
1.9mA typically
Power up
PDWN= 0
3.2mA typically
Normally, the PDWN pin and the RTIME pin
control the operation mode of the HT9032.
When both pins are HIGH, the HT9032 is set at
the power down mode, consuming less than 1 A
of supply current. When a valid power ring ar-
rives, the RTIME pin will be driven below V
T-
and the portions of the part involved in the ring
signal analysis are enabled. This is partial
power up mode, consuming approximately
1.9mA typically. Once the PDWN pin is below
V
T-
,thepartwillbefullypoweredup,andready
to receive FSK. During this mode, the device
current will increase to approximately 3.2mA
(typ). The state of the RTIME pin is now a
don t care as far as the part is concerned. Af-
ter the FSK message has been received, the
PDWN pin can be allowed to return to V
DD
and
the part will return to the power down mode.
