TPS3899中文资料具有可编程感应和复位延迟功能的纳米功率监控器数据手册TI规格书

描述 Description

The TPS3899 is a nano power, precision voltage supervisor with ±0.5% threshold accuracy and programmable sense and reset time delay in a 6-pin space saving 1.5 mm x 1.5 mm WSON package. The TPS3899 is a feature-rich voltage supervisor that offers the smallest total solution size in its class. Built-in hysteresis along with programmable delay prevent false reset signals when monitoring a voltage rail or push button signals.

The separate VDD and SENSE pins allow for the redundancy sought by high-reliability systems. SENSE is decoupled from VDD and can monitor rail voltages other than VDD. Optional use of external resistors are supported by the high impedance input of the SENSE pin. Both CTS and CTR provide delay adjustability on the rising and falling edges of the RESET signals. CTS also functions as a debouncer by ignoring voltage glitches on the monitored voltage rails and operates as a \"manual reset\" that can be used to force a system reset.

The precision performance, best in-class features in a compact form factor, makes the TPS3899 an ideal solution for wide ranging industrial and battery-powered applications such as Factory/Building Automation, Motor Drives, and consumer products. The device is fully specified over a temperature range of –40°C to +125°C (TA).
