Control Signals
Enable Inputs
The ACT8846 features a variety of control inputs,
which are used to enable and disable outputs
depending upon the desired mode of operation.
PWRHLD is a logic inputs, while nPBIN is a unique,
multi-function input.
nPBIN Multi-Function Input
The ACT8846 features the nPBIN multi-function
pin, which combines system enable/disable control
with a hardware reset function. Select either of the
two pin functions by asserting this pin, either
through a direct connection to GA as Manual Reset
input, or through a 50kΩ resistor to GA for 32ms to
enable the IC, or through a 50kΩ resistor to GA for
10s to disable the IC, as shown in Figure 2.
Manual Reset Function
The second major function of the nPBIN input is to
provide a manual-reset input for the processor. To
manually-reset the processor, drive nPBIN directly
to GA through a low impedance (less than 2.5kΩ).
An internal timer detects the duration of the MR
event:
Short Press / Soft-Reset:
If the Manual Reset button is asserted for less than
4s/10s, ACT8846 commences a soft-reset
operation where nRSTO immediately asserts low,
then remains asserted low until the nPBIN input is
de-asserted and the reset time-out period expires.
A status bit, SRSTAT[ ] , is set after a soft-reset
event. The SRSTAT[ ] bit is automatically cleared to
0 after read. After Short Press, set WDSREN[ ] to 1
about 1s after nRSTO de-assert then clear
WDSREN[ ] for properly shutdown sequence.
Long Press / Power-cycle:
If the Manual Reset button is asserted for more
than 4s/10s, ACT8846 commences a power
cycle routine in which case all regulators are turned
off and then turned back on. A status bit, PCSTAT[
], is set after the power cycle. The PCSTAT[ ] bit is
automatically cleared to 0 after read.
nPBSTAT Output
nPBSTAT is an open-drain output that reflects the
state of the nPBIN input; nPBSTAT is asserted low
whenever nPBIN is asserted, and is high-Z
otherwise. This output is typically used as an
interrupt signal to the processor, to initiate a
software-programmable routine such as operating
mode selection or to open a menu. Connect
nPBSTAT to an appropriate supply voltage through
a 10kΩ or greater resistor.
