SGM8771
High Voltage, High Precision,
Single Comparator with Voltage Reference
GENERAL DESCRIPTION
FEATURES
The SGM8771 is a single, high precision voltage
comparator with a 1.225V voltage reference. The device
optimized for high voltage operation from 2.8V to 36V
single supply. It consumes low supply current without
being affected by the supply voltage. Input common
mode voltage is 1.5V lower than +VS. The SGM8771
has an open-drain output structure that needs external
pull-up resistor. It also has a 1.225V voltage reference
that saves external reference and reduces system cost.

High Voltage, High Precision,
SGM8771
Single Comparator with Voltage Reference
DETAILED DESCRIPTION
The SGM8771 is a single, high precision, low power
comparator. The wide input voltage range and power
supply range make the device a good choice for industrial
equipment. Open-drain structure needs external pull-up
resistor. The SGM8771 can be compatible with CMOS
and TTL logics.
If low slew rate transition is needed in system design,
adjusting the load capacitance will change the slew rate.
The heavier capacitive load will slow down the output
voltage transition. This feature will be used to reduce
the interference generated by fast edge of transition
between 1 and 0 in noise-sensitive system.
Output Structure
+VS
In Figure 1, the SGM8771 has an open-drain output
stage. When output is changed from logic high to low,
the changed sink current pulls output pin to logic low.
Beginning this transition, larger sink current is used to
create a high slew rate transit from high to low. Once
the output voltage reaches VOL, it will reduce the sink
current to a just right value to maintain the VOL static
condition. This current-driven open-drain output stage will
significantly reduce the power consumption in application
system.

-VS

APPLICATION INFORMATION
For grounding, unbroken and low-inductance ground
plane is a good choice.
Layout and Bypassing
Good power supply decoupling, layout and grounding
are very important for SGM8771 to realize the full
high-speed capabilities in system, following skills will be
used:
For Layout, use short PCB trace to avoid unwanted
parasitic feedback around the comparator. SGM8771
must be soldered directly to the PCB and the socket is
not recommended.
A 0.1µF to 4.7µF range ceramic capacitor is used to
provide good power supply decoupling. This ceramic
capacitor must be placed as close to VS pin as
possible.
