TLV803EA43RDBZR, Supervisory Circuits Low-power voltage supervisor (reset IC) with active-low open-drain output 3-SOT-23 -40 to 125

Полупроводниковые приборы\ИС для управления питанием\Контрольные цепиTLV80xE/TLV81xE Low Power Voltage SupervisorsTexas 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 ).
