TPS3899/TPS3899-Q1 Precision Voltage Supervisor

Texas Instruments TPS3899/TPS3899-Q1 Precision Voltage Supervisor is a nano power, precision voltage supervisor with ±0.5% threshold accuracy, programmable sense, and reset time delay in a 6-pin space-saving 1.5mm x 1.5mm 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, prevents false reset signals when monitoring a voltage rail or push-button signals.
