G682/G683 Global Mixed-mode Technology Low Voltage Reset IC Features General Description The G682/G683 microprocessor (µP) supervisory circuits monitor system voltages in µP and digital systems. They provide excellent circuit reliability at low cost by eliminating external components. Monitor Supply Voltages from 0.9V to 1.8V ±2% Reset Threshold Accuracy Capacitor-Adjustable Reset Timeout Period tRP (ms) ≅ 2.7 × CD (nF) at VCC=3.3V Low Quiescent Current : 10µA at VCC =3.3V Available in three RESET Output Options 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 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. 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.

The G682L/G682H/G683L assert reset to prevent code-execution errors during power-up, power-down, or brownout conditions. Since the sense 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 threshold, 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 Diagrams. 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 delay set by capacitor connected to CD pin, after Vsen has 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.

Therefore, high-impedance CMOS logic inputs connected to RESET can drift to undetermined voltages. This presents no problem in most applications since most μP and other circuitry is inoperative with VCC below 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 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 supply 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. 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. 3.3V 5V VCC VCC VCC RPULL-UP G682 VSEN Detect Voltage RESET GND R1 100k 5V SYSTEM G683 VSEN RESET GND RESET INPUT GND Figure 5 Figure 4 G683L Open-Drain RESET Output Allows Use with TEL: 886-3-5788833 http://www.gmt.com.tw Ver: 0.8 Feb 27, 2013 14 G682/G683 Global Mixed-mode Technology Package Information SOT-23-5 Package Taping Specification PACKAGE Q'TY/REEL SOT-23-5 3,000 ea TEL: 886-3-5788833 http://www.gmt.com.tw Ver: 0.8 Feb 27, 2013 15 G682/G683 Global Mixed-mode Technology SC-70-5 Package Taping Specification PACKAGE Q’TY/REEL SC-70-5 3,000 ea TEL: 886-3-5788833 http://www.gmt.com.tw Ver: 0.8 Feb 27, 2013 16 G682/G683 Global Mixed-mode Technology DFN1.6X1.6-6 Package Taping Specification PACKAGE Q’TY/REEL DFN1.6X1.6-6 3,000 ea TEL: 886-3-5788833 http://www.gmt.com.tw Ver: 0.8 Feb 27, 2013 17 G682/G683 Global Mixed-mode Technology ADFN1.5X1.5-6 Package Taping Specification PACKAGE Q’TY/REEL ADFN1.5X1.5-6 3,000 ea GMT Inc. does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and GMT Inc. reserves the right at any time without notice to change said circuitry and specifications.
