The supply-voltage supervisor monitors the supply for undervoltage conditions at the SENSE input. During power up, the RESET output becomes active (low) when VCC attains a value approaching 3.6 V. At this point (assuming that SENSE is above VIT+), the delay timer function activates a time delay, after which outputs RESET and RESET go inactive (high and low, respectively). When an undervoltage condition occurs during normal operation, RESET and RESET go active. To ensure that a complete reset occurs, the reset outputs remain active for a time delay after the voltage at the SENSE input exceeds the positive-going threshold value. During power down and when SENSE is below VIT−, the outputs remain active until VCC falls below 2 V. After this, the outputs are undefined. An external capacitor (typically 0.1 μF) must be connected to REF to reduce the influence of fast transients in the supply voltage. Five versions of this circuit are available: • TL7705A (Vt = 4.55 V): Application in TTL-systems and microcomputer systems which require a 5 volt supply (for example, TMS7000) • TL7709A (Vt = 7.6 V): Application in microcomputer systems using the TMS1XXXNLL • TL7712A (Vt = 10.8 V): Application in CMOS, microprocessor, and memory circuits with a 12 volt supply. • TL7715A (Vt = 13.5 V): Application in circuits which operate with a supply voltage of 15 V, as is found often in analog circuits. • TL7702A (Vt = 2.5 V): Application in systems where other supply voltages are used. The required trigger level my be adjusted with an external resistor divider at the SENSE input. 8.2 Functional Block Diagram The functional block diagram is shown for illustrative purposes only; the actual circuit includes a trimming network to adjust the reference voltage and sense-comparator trip point. ~100 µA A.

This voltage source can also be used in applications where a constant voltage source is required. The reference voltage varies less than 10 mV over the supply voltage range of 3.5 V to 18 V. The same stability of the reference voltage is maintained, when the ambient temperature is changed. The reference's voltage varies only 16 mV when the ambient temperature is changed from –40°C to +85°C. 8.4 Device Functional Modes Figure 7 shows the timing of the various signals. In this example the SENSE input is connected to the supply voltage VCC as in typical applications of this device. The minimum supply voltage for which the function of this device is guaranteed is 3.6 V. After power-on, the outputs are undefined until the minimum supply voltage Vres is reached. For the TL77xxA the minimum supply voltage is Vres = 3 V (typical 2.5 V). Beyond the voltage Vres the capacitor CT is first kept discharged, and the outputs stay in the active state (RESET = High, RESET = Low). When the input voltage becomes higher than the threshold voltage Vt, the thyristor is turned off and the capacitor is charged. After a delay, td, the voltage at the capacitor passes the trigger level of the output comparator and the outputs become inactive. The circuit to be initialized is now set to a defined state and starts the correct operation. A. Note: SENSE Input connected to VCC Figure 7.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information This application shows the initialization circuit diagrams for a microprocessor system with supply voltage Vcc = 5 V. The external components required are the decoupling capacitor Cref for the reference voltage and the timing capacitor CT. The outputs of the TL77xxA are open collector outputs. In Figure 8 therefore a pull-up resistor is shown at the RESET output to ensure the correct HIGH level. 9.2 Typical Application µC = Figure 8. Reset Controller Schematic for a Microprocessor 9.2.1 Design Requirements • 5-V microprocessor supply voltage • td = 1.3 ms 9.2.2 Detailed Design Procedure • Select reasonable values for pull-up/pull-down resistors for RESET and RESET. This design uses 10 kΩ. • Choose CT = 0.1 µF to achieve td = 1.3 ms • This design uses only the active-low reset output (RESET) because the example microcontroller resets when the input is Low. 10 Submit Documentation Feedback Copyright © 1983–2016, Texas Instruments Incorporated Product Folder Links: TL7702A TL7705A TL7709A TL7712A TL7715A TL7702A, TL7705A, TL7709A, TL7712A, TL7715A www.ti.com SLVS028K – APRIL 1983 – REVISED SEPTEMBER 2016 Typical Application (continued) 9.2.3 Application Curves 5 5 4.5 4.5 4 RESET Voltage (V) RESET Voltage (V) 4 3.5 3 2.5 2 1.5 3.5 3 2.5 2 1.5 1 1 0.5 0.5 0 0 0 0.5 1 1.5 2 2.5 3 VCC (V) 3.5 4 4.5 0 5 Figure 9.

CAUTION These devices risk being damaged when powered by more than 20 V. 11 Layout 11.1 Layout Guidelines The voltage monitor should be placed on the printed circuit board, where there are no neighboring circuits in the which switch high currents (like bus interface circuits and power switches). When laying out the layout of the printed circuit board, take special care with the interconnects which carry analog signals. Beside the SENSE input these are the CT and Vref terminals. Noise coupled into the CT input will lead to a reduction of the output pulse width. Noise coupled into the Vref input or into the filter capacitor at this input may lead to undesired triggering of the circuit and by this to an undesired RESET pulse. Practice shows, that this malfunction when high currents flow over the interconnects of these capacitors to the GND terminal of the voltage monitor. To avoid these effects, the GND terminals of these capacitors must be connected by the shortest way to the GND terminal of the voltage monitor in so that no currents caused by other circuits flow over these wires. Figure 16 show a layout proposal for the printed circuit board. Furthermore the resistors of the voltage divider at the SENSE input of the TL7702 (R2 and R3 in Figure 16) have to be placed in so, that no noise may be coupled into this circuit. 11.2 Layout Example 1 2 3 4 8 7 6 5 Figure 16.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. Addendum-Page 2 7712AI Samples PACKAGE OPTION ADDENDUM www.ti.com 14-Aug-2021 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of

器件简介: 这些是德州仪器(Texas Instruments)生产的电源监控器集成电路,专为微计算机和微处理器系统的复位控制器设计。它们监控SENSE输入的供电电压,以检测欠压条件。在电源启动期间,当VCC接近3.6V时,RESET输出变为活动状态(低电平)。假设SENSE高于VIT+,延迟计时器功能会激活一个时间延迟,之后RESET和RESET输出变为非活动状态(高和低,分别)。

引脚分配: - CT:外部定时电容引脚 - GND:设备地 - REF:电压参考输出 - RESET:监控复位信号输出 - RESET:监控复位信号输出(反相) - RESIN:复位输入 - SENSE:感应输入 - Vcc:电源供应

参数特性: - 工作电压范围宽:3.5V至18V - 外部可调脉冲持续时间 - 温度补偿电压参考 - 外部可调脉冲持续时间由外部电容CT决定

功能详解: 这些设备在电源电压下降时自动生成复位信号,具有精确的电压传感器和温度补偿的电压参考。它们还提供了外部可调的脉冲持续时间,以适应不同的应用需求。

应用信息: 适用于计算机、平板电脑、智能手机、服务器和音乐播放器等设备。

封装信息: - SOIC(8) - PDIP - SO(8)
