Low Voltage Reset IC
Features
General Description
Monitor Supply Voltages from 0.9V to 1.8V
The G682/G683 microprocessor (µP) supervisory cir-
cuits monitor system voltages in µP and digital sys-
tems. They provide excellent circuit reliability at low
cost by eliminating external components.
±2% Reset Threshold Accuracy
Capacitor-Adjustable Reset Timeout Period
t
RP (ms) ≅ 2.7 × CD (nF) at VCC=3.3V
Low Quiescent Current : 10µA at VCC =3.3V
Available in three RESET Output Options
Since the sense pin is separated from power supply, it
allows the IC to monitor added power supply. Using
the IC with the sense pin separated from power supply
enables output to maintain the state of detection even
when voltage of the monitored power supply drops to
0V. The VSEN pin of G68_ _09T_ is high impedance
and can be used for application of reset threshold
programming.
Push-Pull RESET Output (G682L)
Push-Pull RESET Output (G682H)
Open-Drain RESET (G683L)
Programmable Reset Threshold Application
(G68_ _09T_)
Guaranteed Reset Valid to VCC = 1V
Power-Supply Transient Immunity
SOT-23-5, SC-70-5, DFN1.6X1.6-6 and
ADFN1.5X1.5-6 Packages
Moreover, with the built-in delay circuit, connecting the
delay capacitance pin to the capacitor enables the IC
to provide an arbitrary release delay time.
All of these devices are offered in SOT-23-5, SC-70-5,
DFN1.6X1.6-6 and ADNF1.5X1.5-6 packages.

G682/G683
Global Mixed-mode Technology
Detailed Description
A microprocessor’s (μP’s) reset input starts the μP in a
known state. The G682L/G682H/G683L assert reset to
prevent code-execution errors during power-up,
power-down, or brownout conditions. Since the sense
pin is separated from power supply, it allows the IC to
monitor added power supply. They assert a reset signal
whenever the Vsen supply voltage declines below a
preset threshold (VTH-), keeping it asserted for time de-
lay set by capacitor connected to CD pin, after Vsenhas
risen above the high reset threshold VTH+ (VTH-+VHYS).
The G683L uses an open-drain output, and the
G682L/G682H have a push-pull output stage. Connect
a pull-up resistor on the G683L’s RESET output to
any supply between 0 and 5.5V. The time delay is set
by external capacitor CD, and internal pull up current ICD.
When the voltage at CD pin exceeds the buffer thresh-
old, typically 0.788V, the RESET output high (RESET
output low). The voltage detector and buffer have
built-in hysterisis to prevent erratic reset operation. The
formula of time delay is T (ms) ≅ 2.7×CD (nF). Figure1
and Figure2 show Timing and Functional Block Dia-
grams.

Separated Sense Pin
Since the sense pin is separated from power supply, it
allows the IC to monitor added power supply. Using the
IC with the sense pin separated from power supply
enables output to maintain the state of detection even
when voltage of the monitored power supply drops to
0V.

Adjustable Reset Threshold (G68_ _09T_)
Since the VSEN pin of G68_ _09T_ is high impedance,
it can be used to adjust reset threshold. Connect two
resistors in series from the detected power to GND and
the divided voltage is compared to reset threshold
(0.788V typical). (Figure 3)

G682/G683
Global Mixed-mode Technology
Ensuring a Valid Reset Output Down to VCC = 0V
Multiple Supplies
Generally, the pull-up connected to the G683L will
connect to the supply voltage that is being monitored at
the IC’s VCC pin. However, some systems may use the
open-drain output to level-shift from the monitored sup-
ply to reset circuitry powered by some other supply
(Figure 5). Note that as the G683L’s VCC decreases
below 1V, so does the IC’s ability to sink current at
RESET . Also, with any pull-up, RESET will be
pulled high as VCC decays toward 0. The voltage
where this occurs depends on the pull-up resistor value
and the voltage to which it is connected.
When VCC falls below 0.8V, the G682 RESET output
no longer sinks current and it becomes an open circuit.
Therefore, high-impedance CMOS logic inputs con-
nected to RESET can drift to undetermined voltages.
This presents no problem in most applications since
most μP and other circuitry is inoperative with VCC be-
low 0.8V. However, in applications where RESET must
be valid down to 0V, adding a pull-down resistor to
RESET causes any stray leakage currents to flow to
ground, holding RESET low (Figure 4). R1’s value is
not critical; 100kΩ is large enough not to load RESET
and small enough to pull RESET to ground. A 100kΩ
pull-up resistor to VCC is also recommended for the
G683L if RESET is required to remain valid for VCC <
0.8V.
