Description
The PT7M78xx family microprocessor (P) supervisory
circuits are targeted to improve reliability and accuracy
of power-supply circuitry in
P
systems. These devices
reduce the complexity and number of components
required to monitor power-supply and battery functions.
The main functions are:
1. Asserting reset output during power-up, power-
down and brownout conditions for
P
system.
2. Watchdog functions
3. Manual reset.

Description
Manual-Reset: (CMOS).
Active low. Pull low to force a reset. Reset remains asserted for the duration of
the Reset Timeout Period after MR transitions from low to high. Leave unconnected or connected to VCC if
not used.
Supply Voltage.
Reset is asserted when V
CC
drops below the Reset Threshold Voltage (V
RST
). Reset
remains asserted until V
CC
rises above V
RST
and keep asserted for the duration of the Reset Timeout Period
(t
RS
) once V
CC
rises above V
RST
.
Ground Reference
for all signals.
Watchdog Input (CMOS).
If WDI remains high or low for the duration of the watchdog timeout period
(t
WD
), the internal watchdog timer trigger a reset output. Floating WDI or connecting WDI to a high-
impedance three-state buffer disables the watchdog feature. The internal watchdog timer clears whenever
reset is asserted or WDI occurs a rising or falling edge.
Active-Low Reset Output (Push-Pull or Open-Drain).
It goes low when Vcc is below the reset threshold.
It remains low for about 200ms after one of the following occurs: Vcc rises above the reset threshold
(VRST), the watchdog triggers a reset, or MR goes from low to high.
The inverse of RESET,
active high. Whenever RESET is high, RESET is low.
No connection.
