The TLV853 and TLV863 provide an alternate pinout of the TLV803. During power on, RESET asserts when the supply voltage (VDD) exceeds 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time (td(typ) = 200 ms) starts after VDD exceeds the threshold voltage, VIT. When the supply voltage drops below the VIT threshold voltage, the output is active (low) again. All the devices in this family have a fixed sense-threshold voltage (VIT) set by an internal voltage divider. 2 Applications • • • • • • • • • DSPs, Microcontrollers, and Microprocessors Portable and Battery-Powered Equipment Set-Top Boxes Servers Appliances Programmable Controls Intelligent Instruments Industrial Equipment Automotive Systems The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V.

The TLV853 and TLV863 are both functionally equivalent to the TLV803. These devices output a logic low whenever VDD drops below the negative-going threshold voltage (VIT–). The output, RESET, remains low for approximately 200 ms after the VDD voltage exceeds the positive-going threshold voltage (VIT– + Vhys). These devices are designed to ignore fast transients on the VDD pin. 8.2 Functional Block Diagram TLV8x3 R1 _ VDD Reset Logic + Timer + R2 RESET GND Oscillator Reference Voltage of 1.137 V 8.3 Feature Description 8.3.1 VDD Transient Rejection The TLV803 has built-in rejection of fast transients on the VDD pin. The rejection of transients depends on both the duration and the amplitude of the transient. The amplitude of the transient is measured from the bottom of the transient to the negative threshold voltage of the TLV803, as shown in Figure 8. VDD VITTransient Amplitude tw Duration Figure 8. Voltage Transient Measurement The TLV803 does not respond to transients that are fast duration/low amplitude or long duration/small amplitude. Figure 5 shows the relationship between the transient amplitude and duration needed to trigger a reset. Any combination of duration and amplitude above the curve generates a reset signal.

When VDD is less than 1.1 V, the output transistor turns off and becomes high impedance. The voltage on the RESET pin rises to the voltage level connected to the pull-up resistor. Figure 9 shows a typical waveform for power-up, assuming the RESET pin has a pull-up resistor connected to the VDD pin. VIT- + VHYS VDD 1.1 V td RESET Valid Output Figure 9. Power-Up Response 8.3.3 Bidirectional Reset Pins Some microcontrollers have bidirectional reset pins that act as both inputs and outputs. In a situation where the TLV803 is pulling the RESET line low while the microcontroller is trying the force the RESET line high, a series resistor should be placed between the output of the TLV803 and the RESET pin of the microcontroller to protect against excessive current flow. Figure 10 shows the connection of the TLV803 to a microcontroller using a series resistor to drive a bidirectional RESET line. 3.3 V VCC VDD TLV803S 100 kW RESET Microprocessor 47 kW RST GND Figure 10. Connection To Bidirectional Reset Pin 8.4 Device Functional Modes 8.4.1 Normal Operation (VDD > Power-Up Reset Voltage) When the voltage on VDD is greater than 1.1 V, the RESET signal asserts when VDD is less than VIT– and deasserts when VDD is greater thanVIT–. 8.4.2 Power On Reset (VDD < Power-Up Reset Voltage) When the voltage on VDD is lower than the required voltage to internally pull the asserted output to GND (powerup reset voltage), both outputs are in a high-impedance state. 8 Submit Documentation Feedback Copyright © 2011–2015, Texas Instruments Incorporated Product Folder Links: TLV803 TLV853 TLV863 TLV803, TLV853, TLV863 www.ti.com SBVS157C – APRIL 2011 – REVISED SEPTEMBER 2015 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. 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 9.1.1 Monitoring Multiple Supplies Because the TLV803 has an open-drain output, multiple TLV803 outputs can be directly tied together to form a logical OR-ing function for the RESET line. Only one pull-up resistor is required for this configuration. Figure 11 shows two TLV803s connected together to provide monitoring of a 3.3-V power rail and a 5.0-V power rail. A reset is generated if either power rail falls below the threshold voltage of its corresponding TLV803. 5.0 V 3.3 V 0.1 mF VDD TLV803M RESET 100 kW VIO VCORE Microprocessor RST GND 3.3 V 0.1 mF VDD TLV803S RESET GND Figure 11. Multiple Voltage Rail Monitoring 9.1.2 Output Level Shifting The RESET output of the TLV803 can be pulled to a maximum voltage of 6 V and can be pulled higher in voltage than VDD. It is useful to provide level shifting of the output for cases where the monitored voltage is less than the useful logic levels of the load. Figure 12 shows the TLV803Z used to monitor a 2.5-V power rail, with a logic RESET input to a microprocessor that is connected to 5.0 V and has 5.0-V logic levels.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 12.7 Glossary SLYZ022 — TI Glossary.

器件简介: TLV803、TLV853和TLV863是德州仪器(Texas Instruments)生产的3引脚电压监控器,具有活动低、开漏复位功能。这些器件专为DSP、微控制器和微处理器等处理器系统提供电路初始化和定时监控。

引脚分配: - GND:接地引脚。 - RESET:开漏输出,当复位被断言时,会驱动到低阻抗状态。 - VDD:供电电压引脚。

参数特性: - 3引脚SOT23封装。 - 供电电流:典型值为9μA。 - 精确供电电压监控:阈值电压为2.5V、3V、3.3V、5V。 - 上电复位生成器,固定延迟时间为200ms。 - 与MAX803引脚兼容。 - 温度范围:-40°C至+125°C。

功能详解: 在上电过程中,当供电电压(VDD)超过1.1V时,RESET被断言。之后,监控电路会持续监控VDD,并在VDD低于阈值电压VIT时保持RESET激活状态。内部定时器会延迟输出返回非激活状态(高电平),以确保系统正确复位。延迟时间(典型值为200ms)从VDD超过阈值电压VIT后开始。

应用信息: 适用于DSP、微控制器、微处理器、便携式和电池供电设备、机顶盒、服务器、家电、可编程控制器、智能仪器、工业设备和汽车系统。

封装信息: 所有型号均采用3引脚SOT-23封装,封装尺寸为2.92mm x 1.30mm。
