Applications

Computers Controllers Intelligent Instruments Critical µP and µC Power Monitoring Portable/Battery-Powered Equipment Telecom/Networking Equipment General Description 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. 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, Pin Configuration Typical Application Circuit SOT-23-5/SC-70-5 RESET (RESET) GND CD43VSEN VCC G682/G683 T11/TA1 ()is for G682H SOT-23-5/SC-70-5 RESET (RESET) GND VSEN43VCC CD G682/G683 T12/TA2 Detect Voltage VCC VSEN GND RESET (RESET) CD *100kΩ *The 100kΩ pull up resistor is only for G683L **Adjustable reset threshold voltage is only for G68__09T_.

Ver: 0.8 Feb 27, 2013 TEL: 886-3-5788833 http://www.gmt.com.tw G682/G683Global 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 s upply, 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 C D pin, after Vsen has risen above the high reset threshold V TH+ (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 C D 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.
