Description for the TPS3899

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).

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
