TLV80xE/TLV81xE Low Power Voltage Supervisors

Texas Instruments TLV80xE/TLV81xE Low Power Voltage Supervisors are enhanced alternatives to the TLV803, TLV853, TLV809, LM809, TPS3809, and TLV810. These devices offer lower supply current for battery-powered applications, higher accuracy, wider temperature range, and lower power-on-reset (V_POR) for increased system reliability. The Texas Instruments TLV80xE/TLV81xE are low I_Q (250nA typical, 1µA max) voltage supervisory circuits (reset ICs) that monitor V_DD voltage level. These devices initiate a reset signal whenever supply voltage V_DD drops below the factory programmed falling threshold voltage, V_IT–. The reset output remains low for a fixed reset time delay t_D after the V_DD voltage rises above the rising voltage threshold (V_IT+), which is equivalent to the falling threshold voltage (V_IT-) plus hysteresis (V_HYS).
