SGM820
High-Accuracy Supervisory Circuit
with Programmable Watchdog Timer
GENERAL DESCRIPTION
FEATURES
The SGM820 is a high-accuracy supervisory circuit with
programmable watchdog timer, which can realize the
under-voltage threshold accuracy of less than 1% from
-40℃ to +125℃. It provides ten reset threshold voltage
options for 1.8V, 2.5V, 3V, 3.3V and 5V voltage
monitoring.
● Precision Fixed Detection Options: 1.8V, 2.5V, 3V,
3.3V and 5V
● High-Accuracy Voltage Threshold (< 1%)
● Hysteresis: 0.5% (TYP)
● Supply Voltage Range: 1.6V to 6.5V
● Ultra-Low Supply Current: 1.2μA (TYP)
● Factory-Set ±15% Accuracy Watchdog Timeout
and Reset Delays
The nRESET delay of the SGM820 has
a
high-precision delay timing. Due to its accurate
hysteresis, the SGM820 is very suitable for using with
strict tolerance systems.
● User-Programmable Watchdog Timeout
● Watchdog Disable Function
● Manual Reset Input (nMR)
The SGM820 has a programmable watchdog timer.
Users can program the timeouts through an external
capacitor or the default factory settings. In addition,
users can disable the watchdog through logic pins to
prevent accidental timeouts during development.
● Open-Drain nRESET Output
● -40℃ to +125℃ Operating Temperature Range
● Available in Green TDFN-3×3-8L and
TDFN-2×2-8L Packages
APPLICATIONS
The SGM820 is available in Green TDFN-3×3-8L and
TDFN-2×2-8L packages. It operates over an ambient
temperature range of -40℃ to +125℃.

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
NOTE:
1. It is recommended to use the standard timing with a CCWD
capacitor from 0.1nF to 1000nF,and offer tWD_TYP from 0.613ms
to 3.33s accordingly; If using extended timing, offer tWD_TYP from
0.613ms to 3.33s accordingly.
