The TLV840 family of voltage supervisors or reset ICs
can operate at high voltage levels while maintaining
very low quiescent current across the whole VDD and
temperature range. TLV840 offers best combination of
low power consumption, high accuracy and low
propagation delay (tp_HL= 30 μs typical).
Reset output signal is asserted when the voltage at
VDD drops below the negative voltage threshold
(VIT-). Reset signal is cleared when VDD rise above
VIT- plus hysteresis (VHYS) and the reset time delay
(tD) expires. Reset time delay can be programmed by
connecting a capacitor between the CT pin and
ground for TLV840C and TLV840M. For a minimum
reset delay time the CT pin can be left floating.
TLV840N does not offer a programmable delay and
offers fixed reset delay timing options: 40 μs, 2 ms, 10
ms, 30 ms, 50 ms, 80 ms, 100 ms, 150 ms, 200 ms.
Additional features: Low power-on reset voltage
(VPOR), built-in glitch immunity protection for VDD,
built-in hysteresis, low open-drain output leakage
current (Ilkg(OD)). TLV840 is a perfect voltage
monitoring solution for industrial applications and
battery-powered / low-power applications. TLV840CADL11DBVR
