TPS3125 的说明

The TPS312x family of voltage supervisory circuits provides voltage monitoring down to 1.2V rails and timing supervision, primarily for DSP and processor-based systems. All devices in the family monitor the power rail and assert RESET output when the power rail is under the threshold voltage target (VIT-). The threshold voltage is programmed into the device to minimize external components. Built-in hysteresis prevents false triggering. The RESET output is not valid for supply voltage (VDD) under 0.75 V. The TPS312x family includes devices with active high output for use as disable during malfunction and active low outputs for most systems where high output indicates properly functioning system.

The TPS3123/3124/3128 also include the watchdog timer functionality to monitor timely digital pulses from the processor and issue an alert if the expected pulse does not arrive on time due to potential software freeze or hang. Such integration of supply rail monitoring and the watch dog timer feature is very helpful in always on systems, such as Factory Automation and Communications Infrastructure.

In addition the TPS3123/5/6/8 devices incorporate a manual reset input, MR, to force RESET triggered by an event unrelated to the voltage rail monitoring of the pulses monitored by the watch dog timer. A low level at MR causes RESET to become active. The TPS3124 devices do not have the input MR, but include a high-level output RESET same as the TPS3125 and TPS3126 devices.

All devices in the family are available in a 5-pin SOT23-5 package and are characterized for operation over a temperature range of –40°C to +85°C.

包装方式

您可以根据器件数量选择不同的包装方式,包括完整卷带、定制卷带、剪切带、管装或托盘。

定制卷带是从整盘卷带上剪下来的具有连续长度的剪切带,是一种可以对特定数量提供产品批次及生产日期跟踪的包装方式。根据行业标准,使用黄铜垫片在剪切带两端各连接一个 18 英寸的引带和尾带,以直接送入自动组装机。涉及定制卷带的 TI 订单将包含卷带费用。

剪切带是从整盘卷带上剪下来的特定长度的编带。根据所申请器件数量的不同,TI 可能会使用多条剪切带或多个盒子进行包装。

TI 通常会根据库存情况选择将管装托盘器件以盒装或者管装或托盘形式发货。所有器件均会按照 TI 内部规定的静电放电和湿敏等级保护要求进行包装。
