3 Description
The TLV840-Q1 device is a voltage supervisor or
reset IC that can operate at wide input voltage levels
from 0.7 V to 6 V while maintaining very low quiescent
current across the whole VDD and temperature range.
TLV840-Q1 offers the 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 a minimum reset delay time the CT pin
can be left floating. The TLV840-Q1, with its manual
reset pin (MR), offers program flexibility by forcing the
system into a hard reset when the pin is asserted.
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-Q1 is a perfect voltage
monitoring solution for automotive applications and
battery-powered / low-power applications.
