Description for the TPS3850
The TPS3850 combines a precision voltage supervisor with a programmable window watchdog timer. The TPS3850 window comparator achieves 0.8% accuracy (–40°C to +125°C) for both overvoltage (VIT+(OV)) and undervoltage (VIT–(UV)) thresholds. The TPS3850 also includes accurate hysteresis on both thresholds, making the device ideal for use with tight tolerance systems. The supervisor RESET delay can be set by factory-programmed default delay settings, or programmed by an external capacitor. The factory-programmed RESET delay features a 15% accuracy, high-precision delay timing.
The TPS3850 includes a programmable window watchdog timer for a wide variety of applications. The dedicated watchdog output (WDO) enables increased resolution to help determine the nature of fault conditions. The window watchdog timeouts can be set by factory-programmed default delay settings, or programmed by an external capacitor. The watchdog can be disabled via logic pins to avoid undesired watchdog timeouts during the development process.
The TPS3850 is available in a small 3.00-mm × 3.00-mm, 10-pin VSON package.

Select a carrier option
NEW - 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
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.
