SGM853
Low Power Reset Timer
with Two Voltage Detector Functions
GENERAL DESCRIPTION
FEATURES
The SGM853 is a reset timer with dual voltage detector
featuring low power and small solution size for
applications requiring a highly integrated solution.
● Low Power Consumption
● Output Options:
2 Outputs: Push-Pull 1×
1 Output: Push-Pull 2×
As a reset timer, the SGM853 has an input (RESET pin)
and a fixed delay push-pull 1× output (RESET_OUT pin).
It generates a low-level reset signal for 500ms (TYP) if
the input has a low-level voltage for 8s (TYP). Then the
reset signal returns to high for subsequent loads reset.
● Available in a Green UTQFN-1.6×1.6-12AL Package
APPLICATIONS
Smart Phones
Tablet PCs
The SGM853 also has two voltage detector functions
with 4 inputs and 2 outputs including a push-pull 1×
output and a push-pull 2× output. The 2× output
provides greater source and sink current. On the one
side, the ALL_PG output pin indicates whether the 3
input pins (SUS_PG, VCC_PG and AUX_PG) are in a
high-level voltage at the same time. If the above 3 input
pins are high at the same time, the ALL_PG output pin
is set to high, and vice versa. On the other side, the
PROCHOT_OUT output pin generates a fixed 12ms
delay time and indicates whether the PROCHOT input
pin is in a high-level voltage. If PROCHOT rises to
high-level voltage, PROCHOT_OUT rises after a fixed
12ms delay time, and PROCHOT_OUT falls
immediately when PROCHOT falls.

Low Power Reset Timer
SGM853
with Two Voltage Detector Functions
APPLICATION INFORMATION
Detector 1: ALL_PG
The SGM853 is both a reset timer and a dual voltage
detector that features low power and small solution size
for applications requiring a highly integrated solution.
The ALL_PG output pin monitors 3 input pins at the
same time: SUS_PG, VCC_PG and AUX_PG pins. If
the application scenario requires voltage detection on
up to 3 power rails, connect the power rail to the above
three input pins respectively.
Reset Timer
A reset event occurs and forces the reset input (RESET
pin) in a low-level input voltage for at least 8s. The
RESET_OUT generates a low-level reset signal for
500ms to shut down the subsequent loads or PMIC.
Then the reset signal returns to a high-level voltage
until the input pin is in the next low-level state for more
than 8s.
Detector 2: PROCHOT and PROCHOT_OUT
The PROCHOT_OUT pin is used to monitor PROCHOT
input pin. If the PROCHOT input rises to a high-level
voltage, the PROCHOT_OUT rises after a fixed delay
time of 12ms, and PROCHOT_OUT falls immediately
when PROCHOT in low-level voltage. If PROCHOT
keeps in high-level voltage within 12ms, the
PROCHOT_OUT remains low.
If the RESET is released and returns to high-level
voltage within 8s, the counter resets and the
RESET_OUT remains high.
